Babies should not drink juice at all before 12 months old, and even after that it should be rare, limited, and always 100% fruit juice in small amounts.

Quick Scoop: When Can Babies Drink Juice?

Pediatric experts and major health organizations now say no juice before age 1 for almost all babies.

Here’s the simple breakdown:

  • 0–6 months:
    • Breast milk or formula only; no juice, no water.
  • 6–12 months:
    • Start solids and give sips of water if needed, but still no juice. Whole, soft fruit (mashed or purĂ©ed) is preferred over juice.
  • After 12 months:
    • You can offer a little juice, but it’s optional and should be limited and diluted.

Think of juice as an occasional treat, not a daily drink.

What the Latest Guidelines Say

Current guidance (including the American Academy of Pediatrics and major children’s hospitals) is very consistent:

  • Under 1 year:
    • “No juice” is the standard recommendation, unless a doctor gives a specific medical reason (for example, constipation).
  • Ages 1–3 years:
    • Up to about 4 ounces (120 ml) per day of 100% fruit juice, max.
  • Ages 4–6 years:
    • About 4–6 ounces (120–180 ml) per day, max.
  • Ages 7+:
    • Up to 8 ounces (1 cup / 240 ml) per day.

Even after age 1, experts stress offering water and milk first, and fruit in its whole form (mashed, soft pieces) instead of juice.

Why Wait to Give Juice?

There are a few big reasons doctors are cautious about juice for babies:

  • It doesn’t add meaningful nutrition for infants compared with breast milk or formula.
  • It’s high in natural sugars, which:
    • Can lead to tooth decay.
    • Add extra calories without helpful protein or fat.
    • May contribute to excess weight gain.
  • It can upset tiny stomachs and cause diarrhea in some babies and toddlers.
  • It can teach a strong preference for sweet drinks early on, making water and less-sweet foods harder to accept later.

Whole fruits, on the other hand, offer fiber that helps digestion, slows sugar absorption, and supports healthy bowel movements.

When Juice Might Be Used Medically

There is one common exception you might hear about in parenting forums: constipation.

  • Some pediatricians will recommend small amounts of 100% apple, pear, or prune juice in certain cases of constipation.
  • Even then, many doctors still prefer using the fruit itself (like purĂ©ed prunes or pears) because the fiber usually works better than juice alone.
  • This should always be done with your pediatrician’s guidance, especially for a baby under 1.

How to Offer Juice Safely (After Age 1)

If you decide to give your toddler juice after their first birthday:

  • Choose 100% fruit juice only, no added sugar or sweeteners.
  • Limit the amount:
    • Ages 1–3: keep it at or under 4 oz (120 ml) per day.
  • Dilute it with water (for example half juice, half water) to reduce sugar and protect teeth.
  • Offer it in an open cup or straw cup, not a bottle, to lessen constant exposure on teeth.
  • Do not use juice as a sleep drink, comfort drink, or all-day sip cup.

A helpful way to think of it: if your child drinks juice, it should be at mealtimes, in small amounts, and not every day.

[1][4] [5][1][4] [8][1][4][5] [1][4] [8][4][5] [4] [5][8][4] [4]
Age Can they have juice? Recommended daily amount Better options
0–6 months No 0 oz Breast milk or formula only
6–12 months No (except rare medical advice) 0 oz Breast milk/formula, water sips, soft/purĂ©ed fruits
1–3 years Optional Up to 4 oz (120 ml) of 100% juice Water, milk, whole fruits
4–6 years Yes, limited 4–6 oz (120–180 ml) per day Water, milk, fruit pieces
7+ years Yes, limited Up to 8 oz (240 ml) per day Water, milk, whole fruit

A Quick Everyday Example

Imagine a 14‑month‑old who loves food and is just getting curious about what’s in everyone’s cup.

  • At breakfast, you might offer water and milk, plus some soft banana pieces instead of orange juice.
  • At a family brunch, you could pour 2 oz of 100% orange juice into a cup, add 2 oz of water, let them enjoy it with food, and then switch back to water the rest of the day.

This way, your child gets to explore new flavors, but you still protect their teeth, appetite, and long-term habits.

Bottom line: For “when can babies drink juice,” the safest and most widely supported answer is after 12 months , in small, limited amounts of 100% fruit juice—if at all—while prioritizing breast milk or formula in the first year and whole fruits, water, and milk after that.
