Can Babies Have Pedialyte? Age, Amounts, and Warning Signs

Call a doctor before giving Pedialyte to a baby younger than 12 months. Babies can lose too much fluid when they vomit or have diarrhea. The doctor can tell you which product to use and how much.

Continue breastfeeding or offer properly mixed formula if your baby can drink safely. Pedialyte replaces lost water and salts. It does not stop vomiting or diarrhea.

Watch wet diapers, feeding, breathing, and how your baby responds. Call a doctor if wet diapers decrease or your baby seems unusually sleepy. Call emergency services if your baby struggles to breathe or has blue lips.

When should parents consider giving Pedialyte to their child?

Ask about Pedialyte when vomiting or watery diarrhea makes feeding difficult. Call promptly if your baby has fewer wet diapers than usual. Tell the doctor how many times your baby vomited or had diarrhea. Add when your baby last fed and when you last saw a wet diaper. Have the package nearby if you already bought Pedialyte.

Pedialyte is a drink that replaces some water and salts lost during illness. Doctors call drinks like it oral rehydration solutions, or ORS. The sugar and salts help the body take in water. Pedialyte cannot end the illness, and a baby may need an exam. Abbott describes how Pedialyte works.

Call again if vomiting continues, feeds stop, or wet diapers decrease. Seek urgent medical help when your baby cannot drink enough fluid. Never wait for several warning signs to appear together.

What Pedialyte can do

Pedialyte can replace water and salts lost through vomiting or diarrhea. A doctor may recommend measured amounts when milk feeds are difficult. Breast milk and formula still provide the food your baby needs. Pedialyte cannot replace either one or stop the illness. Tell the doctor if your baby coughs or struggles to swallow. Trouble breathing or blue lips needs emergency help before another drink.

  • Replaces some water and salts lost during vomiting or diarrhea.
  • Comes in different products with different age directions.
  • Needs an amount from a doctor for babies younger than 12 months.
  • Cannot replace breast milk, formula, or a medical exam.

Can a baby younger than 12 months have Pedialyte?

Yes, a doctor may recommend Pedialyte for a baby younger than 12 months. Abbott tells parents to consult a doctor before giving any amount to an infant. That instruction still applies after your baby reaches six months. It also applies when you used Pedialyte during an earlier illness.

Babies can become dehydrated more quickly than older children. Tell the doctor about early birth, kidney problems, diabetes, and medicines. Mention any change in feeding or wet diapers. The doctor may ask to examine your baby before recommending fluids at home.

Check three details before opening Pedialyte

Know how old your baby is and how much your baby weighs. Count recent vomits, watery stools, feeds, and wet diapers. Read the full name on the Pedialyte package aloud. Abbott sells several products, and their age directions differ. Tell the doctor about health conditions and medicines, too. Ask for the amount, minutes between drinks, and when to call again.

  1. Baby: Share age, weight, health conditions, and medicines.
  2. Illness: Count vomits, watery stools, feeds, and wet diapers.
  3. Product: Read the full product name and form from its package.

Before opening the bottle

Three details for the doctor

Have these details ready when you call.

  1. 01
    Age and weight

    Share how old your baby is and their latest weight.

  2. 02
    Recent symptoms

    Count vomits, watery stools, feeds, and wet diapers.

  3. 03
    Product name

    Read the full name and form aloud.

Two eight-month-old babies can need different advice. One may nurse normally while the other vomits every feed. Call again if your baby gets worse after the first conversation.

What should you offer before Pedialyte?

For babies from six months until their first birthday, offer breast milk or undiluted formula first. If your baby cannot tolerate milk feeds, ask about an oral rehydration solution. That advice comes from the American Academy of Pediatrics. Babies younger than six months need prompt medical advice when vomiting or diarrhea affects feeding.

During vomiting

What to offer, in order

Follow the advice given for your baby.

  1. 01
    Start with milk

    Offer breast milk or properly mixed formula.

  2. 02
    Ask about Pedialyte

    Use the product and amount the doctor recommends.

  3. 03
    Watch and report

    Track drinking, vomiting, stools, and wet diapers.

Continue feeds whenever your baby can swallow without trouble. Never add extra water to formula. Call promptly if your baby refuses feeds or has fewer wet diapers. A very young baby can become ill before every warning sign appears.

For a breastfed baby

Continue breastfeeding if your baby can nurse and swallow safely. A baby with an upset stomach may take shorter feeds more frequently. For example, a seven-month-old might nurse briefly, pause, then nurse again. Watch for vomiting after feeds and count wet diapers. Call if your baby refuses feeds or cannot hold milk down. Ask if Pedialyte is needed between nursing sessions.

The American Academy of Pediatrics supports continued breastfeeding during diarrhea. Some breastfed babies can get enough fluid from nursing alone. Your doctor can decide if an extra rehydration drink is needed.

For a formula-fed baby

Mix formula with the exact water amount printed on its package. Extra water can reduce nutrition and upset the balance of salts. Continue usual formula if your baby can drink without trouble. If every bottle comes back up, call a doctor. Report how much your baby drank and when the last diaper was wet. Mention coughing, choking, or weak sucking during feeds.

Use separate containers for formula and Pedialyte. If a doctor recommends Pedialyte, ask when regular formula feeds should continue. Avoid a long break from milk without medical instructions.

What affects infant Pedialyte dosage?

There is no single Pedialyte amount for every baby younger than 12 months. Abbott directs infant dosage questions to a doctor. Tell the doctor about weight, symptoms, milk intake, and health conditions. Liquid, powder, and freezer pops have different age directions.

Ask for the amount in milliliters and minutes between drinks. Use an oral syringe or another measuring tool the doctor recommends. Household spoons can measure liquid inaccurately.

How much Pedialyte can a 5-month-old have?

A five-month-old needs a doctor to choose the Pedialyte amount. At five months, babies can lose too much fluid quickly. Tell the doctor when feeding changed and how many diapers were wet. Share how much your baby weighs, medicines, and health conditions. The doctor may want to see your baby before advising home treatment. Never use an amount copied from an older child chart.

Ask which product to use, how much to offer, and when to stop. Continue breast milk or formula unless the doctor recommends another feeding plan.

Can a 6-month-old have Pedialyte?

Yes, a doctor may recommend Pedialyte for a six-month-old baby. Abbott still asks parents to call a doctor after six months. No single amount suits every six-month-old baby. Tell the doctor how much your baby weighs. Mention repeated vomiting, watery stools, or fewer wet diapers. Ask if milk feeds should continue.

Write down the amount and the time between drinks. Call again if your baby cannot swallow safely or keeps vomiting.

How much Pedialyte can an 8-month-old have?

An eight-month-old also needs advice for the illness happening now. Tell the doctor how much milk your baby drank. Count vomits, watery stools, and wet diapers since symptoms began. Read the full Pedialyte product name from the package. Ask how many milliliters to offer each time. Ask how long to wait between drinks and when to stop.

An amount from an earlier illness may be wrong now. Call again when symptoms change.

How much Pedialyte can a 9-month-old have?

A nine-month-old has no standard Pedialyte dose either. Share a recent weight if you have one. Describe if your baby wakes and responds as usual. Mention feeds, vomiting, watery stools, and wet diapers. Ask when to continue regular milk feeds. Write down the product name and amount before offering a drink.

If your baby becomes hard to wake, seek emergency help. Never wait to finish a Pedialyte schedule.

Why no infant dose chart appears here

A printed chart cannot account for a baby who struggles to swallow. It also cannot assess rapid changes in vomiting or wet diapers. Abbott asks parents to consult a doctor for infants younger than one year. A number copied from another baby could be wrong for yours. Ask for an amount, timing, and a point to call again.

Write the instructions where another adult can see them. Call for new advice if symptoms change or feeding becomes difficult.

How should you offer Pedialyte after medical approval?

Use the product and amount recommended for your baby. Follow the schedule from your doctor. Small, frequent drinks may help when vomiting continues. Measure each drink with a clean oral syringe or measuring cup. Write down feeds, vomits, stools, and wet diapers.

  1. Read the full product name and age directions.
  2. Wash your hands and use a clean measuring tool.
  3. Measure the amount the doctor gave you.
  4. Offer it at the time the doctor recommended.
  5. Call again if vomiting continues or wet diapers decrease.

Never force liquid into a baby who coughs or struggles. Stop offering drinks if swallowing becomes difficult. Call emergency services if breathing becomes hard or lips turn blue.

Never add juice, sugar, formula, or extra water to ready-to-drink Pedialyte. Added liquids change its measured sugar and salt mix. Abbott warns against mixing other drinks into Pedialyte. Throw away liquid left in a cup your baby used.

Which Pedialyte form can a baby use?

Ask for the full product name, including its form. Pedialyte names and package designs have changed. Similar-looking products can have different uses and age directions. Read the front and back labels during the doctor call. Abbott lists the current product lines.

Read the whole package

Age rules differ across products

Read the full name and age directions.

Call first
Ready-to-drink liquid

Ask a doctor before any amount for an infant.

Younger than 12 months: no
Powder packs

Abbott excludes babies younger than one year.

Younger than 12 months: no
Freezer pops

Abbott excludes babies younger than one year.

Ask before use
Sport and Zero Sugar

These products have different intended uses.

Ready-to-drink liquid

Ready-to-drink Pedialyte already contains its required water. Ask the doctor if that exact liquid suits your baby. Pour only the amount the doctor recommended into a clean container. Never add water, formula, juice, or sugar. Check the expiration date before opening the bottle. Write the opening time on the bottle if you may use it again.

Refrigerate the opened bottle and discard it after 48 hours. Follow any stricter directions printed on the package.

Powder packs

Abbott excludes children younger than one year from Pedialyte powder packs. The manufacturer states that age limit in its product answers. Never prepare a powder pack for a baby younger than 12 months. Ask the doctor about a suitable ready-to-drink product. Powder instructions for older children cannot remove the infant age limit.

Check the package when shopping, since product names can change. Never assume two Pedialyte forms have the same directions.

Freezer pops

Abbott also excludes children younger than one year from Pedialyte freezer pops. Abbott lists the same age limit for freezer pops. Never offer one to a baby younger than 12 months. Freezing regular Pedialyte liquid is also outside Abbott product directions. Ask about a suitable liquid if a doctor recommends rehydration.

Read the age directions each time you buy a product. A familiar brand name cannot prove a product is safe for infants.

Sport, zero-sugar, and other lines

Pedialyte Sport and Zero Sugar products have different intended uses. Use only the product named during a doctor call. Read the complete product name aloud before giving any amount. A photo of the label can help when two bottles look alike. Ask a pharmacist or doctor if you cannot identify the product.

Can Pedialyte replace breast milk or formula?

No. Pedialyte cannot replace the food in breast milk or formula. Milk provides calories and nutrients your baby needs to grow. Pedialyte can replace some water and salts lost during illness. Ask the doctor how to offer both if your baby needs Pedialyte.

Continue milk when your baby can drink safely

Continue breastfeeding when your baby can nurse and swallow. Offer properly mixed formula if your baby can drink it. Shorter feeds may help when your baby vomits after larger ones. Ask the doctor when to return to usual feed amounts. A baby who has started solids can return to familiar foods as appetite returns. Milk remains an important part of feeding.

Call if your baby refuses milk or has fewer wet diapers. CDC guidance supports continued feeding during childhood stomach illness, including breastfeeding.

Never mix inside one bottle

Never pour Pedialyte into a bottle of formula. Abbott warns that mixing changes both drinks. It can also make the formula thick or clumpy. Prepare formula with the exact water amount printed on its package. If the doctor recommends Pedialyte, measure it separately. Separate containers help another adult follow the same instructions.

Continue breastfeeding or formula as the doctor recommends. Ask when to return to usual feeds if vomiting changed your feeding schedule. Never replace several milk feeds with Pedialyte without medical instructions.

What can replace Pedialyte during illness?

A different oral rehydration drink may be suitable for your baby. Ask a doctor or pharmacist about the exact product first. Read its age directions and full name from the package. Never assume another drink has the same sugar and salt mix. Use the amount recommended for that product and your baby.

Before using another rehydration drink

Check the product age range and if it is ready to drink. Tell the doctor if it is a powder or another form. Powder products have mixing rules and may have age limits. Take a photo of the front and directions panel. Ask for the amount and when to call again. Buy the exact form named during the conversation.

Never switch products midway through illness without checking. The same brand can sell products for different uses.

Drinks that cannot replace infant ORS

Sports drinks, soda, and juice have different sugar and salt amounts. Plain water cannot replace salts lost through repeated watery diarrhea. Coconut water and plant milk are different from an oral rehydration drink. Homemade sugar-and-salt mixtures can contain serious measuring errors. Never use these drinks in place of doctor-recommended Pedialyte.

Ordinary water for a healthy older baby is a separate question. During vomiting or diarrhea, ask which drink your baby needs. See our baby water article for everyday water questions. CDC recommends commercially prepared rehydration drinks when they are available.

Which dehydration signs need medical help now?

Call a doctor if wet diapers become fewer than usual. The American Academy of Pediatrics lists fewer than six wet diapers in one day as an infant warning sign. A dry mouth, fewer tears, or unusual sleepiness also warrants a call. Any one concerning change deserves attention.

Know when to call

Two levels of medical help

One concerning sign can be enough.

Call a doctor promptly
Changes to report
  • Fewer wet diapers than usual
  • Dry mouth or fewer tears
  • Less feeding or unusual sleepiness
Emergency help
Danger signs
  • Will not wake or respond
  • Hard breathing or blue lips
  • Pale, blotchy skin that feels cold

Call a doctor promptly

Notice how your baby differs from their normal behavior. Count wet diapers and note when the last one appeared. Tell the doctor if feeds have dropped or vomiting continues. Mention watery stools, a dry mouth, or fewer tears. A sunken soft spot can also signal dehydration. Call after one concerning change appears.

  • Your baby has fewer wet diapers than usual.
  • Your baby drinks less or cannot hold feeds down.
  • The mouth looks dry or crying produces fewer tears.
  • The soft spot on the head looks sunken.
  • Your baby seems much sleepier or fussier than usual.

Get emergency help right away

Call emergency services if you cannot wake your baby or breathing becomes hard. Blue lips or no response also need immediate help. A pale or blotchy baby who feels unusually cold needs emergency help. Stop offering drinks if your baby struggles to swallow. Call before trying another drink.

  • Your baby is hard to wake or barely responds to your voice.
  • Breathing looks hard, or the lips turn blue.
  • Your baby looks pale or blotchy and feels cold.

Go to an emergency department if vomit is green or contains blood. The American Academy of Pediatrics lists both as urgent vomiting signs. Blood in stool also needs prompt medical advice. If your baby is younger than three months, call a doctor immediately for a temperature of 100.4°F (38°C) or higher. The American Academy of Pediatrics lists that fever threshold.

What should you tell the doctor?

Start with how old your baby is and how much they weigh. Mention medicines and health conditions. Then report the number of vomits and watery stools. Count wet diapers during the last 24 hours. Tell the doctor when your baby last fed. Mention fever, green vomit, blood, or unusual sleepiness. Read the full Pedialyte product name if you bought one.

A useful report might include three vomits and two feeds since morning. Add when you last saw a wet diaper. The times help the doctor assess how quickly things changed. Ask for the Pedialyte amount and the time between drinks. Repeat the instructions aloud before ending the call.

What if your baby refuses or vomits Pedialyte?

Call the doctor if your baby keeps vomiting the recommended drinks. Ask what to offer next and if your baby needs an exam. The American Academy of Pediatrics recommends small, frequent drinks when vomiting makes larger feeds difficult. For an infant, follow the amount and timing chosen during your call.

Never force liquid into a baby who coughs or chokes. Put the drink down if swallowing becomes difficult. Call emergency services for trouble breathing or blue lips. Tell the doctor about the last wet diaper and the latest vomit. Go to an emergency department for green or bloody vomit. Call a doctor immediately for severe belly pain.

How do dehydration signs change as illness worsens?

Dehydration can worsen without following neat stages parents can diagnose. Fewer wet diapers may be the first change you notice. A baby may then become sleepier or drink less. Trouble breathing, difficulty waking, or unusually cold skin can signal serious illness. Call when a warning sign appears; never wait for a table to match.

Doctors use several signs together when assessing dehydration. CDC guidance notes that mild and moderate dehydration can be difficult to separate from signs alone. The table below shows what to notice and how urgently to respond. Only a clinician can diagnose a dehydration level.

What you noticeCall a doctor promptlyGet emergency help
Wet diapersFewer than usual, or none for many hours.Get help for danger signs, even after a recent wet diaper.
Feeding and vomitingDrinks much less, vomits repeatedly, or cannot hold feeds down.Struggles to swallow or breathe during a drink.
BehaviorMuch sleepier or fussier than usual.Hard to wake or unresponsive.
Eyes and mouthFewer tears, dry mouth, or sunken-looking eyes.Seek urgent assessment if these appear with cold, blotchy skin.
Skin and breathingBreathing becomes quicker than usual.Lips turn blue, breathing becomes hard, or skin becomes cold and blotchy.

Several signs can appear together, but one danger sign is enough. NICE describes changes in response, urine, skin color, and breathing during clinical assessment. Tell a doctor what you see without naming a dehydration stage.
