Can Babies Have Soda? No, and Here Is Why

Soda is not a drink for babies or toddlers. It is carbonated sugar water, often acidic and sometimes caffeinated, with nothing a growing child needs. Pediatric and nutrition groups recommend keeping all sweetened drinks out of young children's diets.

Soda is one of the clearest no-gos for a young child, and yet it is easy for a sip to get offered at a party or a restaurant. It is carbonated sugar water: a single can often carries more added sugar than a toddler should have in an entire day, colas add caffeine that a small child should not have, and the acid is rough on tooth enamel. Health groups that set beverage guidance for early childhood are blunt about it, recommending that all sweetened drinks be kept out of young children's diets.1 There is no version of soda, including diet soda, that a baby or toddler needs.

⚠️ Soda has no place in a baby or toddler's diet. Sweetened drinks are recommended against for young children, and caffeinated colas add a stimulant a small child should not have.1

Why it matters: A single can can hold more sugar than a young child should have in a day, and the acid plus sugar is hard on new teeth.12

Prep School: how to prepare soda for baby-led weaning (BLW) and purées

Under 12 monthsNo soda, and no other sweetened or carbonated drinks. Breast milk or formula plus small sips of water with meals is all a baby needs.
12 months and upWater and plain milk are the drinks. Soda stays off the menu; if older family members drink it, keep cups out of a toddler's reach so a curious child does not help themselves to a sugary, caffeinated sip.
A better fizzy ideaIf it is the bubbles a child is curious about, plain sparkling water with a few pieces of fruit gives the fizz without the sugar, acid load, or caffeine. Keep it occasional, since carbonation can still be a lot for a small stomach.

Is soda safe? Choking & prep

Soda is not a choking hazard, but it is a poor fit for a baby or toddler in several ways. The sugar and acid together erode tooth enamel, especially when sipped over time. Colas and some other sodas contain caffeine, a stimulant young children should not have, which can affect sleep and make a small child jittery. The carbonation can cause gas and discomfort in a little belly. And nutritionally it offers nothing, while filling a child up so they want less milk and food. Diet sodas swap sugar for low-calorie sweeteners, which are also not recommended for children under 5, so they are not a workaround.1

Nutrition

Soda is sugar, water, carbonation, coloring, and flavoring, with caffeine in colas and many others. It provides no protein, fat, fiber, vitamins, or minerals that a growing baby needs. The calories it does add are the definition of empty: they crowd out the nutrient-dense milk and food this age depends on, and the sugar feeds the bacteria that cause tooth decay. For a baby or toddler there is simply no nutritional reason to include it.

Goes well with

Plain water in an open or straw cup · Whole milk (after 12 months) · Sparkling water with a few fruit pieces (occasional, older toddlers) · Whole fruit for natural sweetness

Storage & freezing

Nothing to keep on hand for a baby. If soda is in the house for adults, store it out of a young child's reach and sight, and make water and milk the drinks a toddler sees at the table, so soda does not become something they expect.

Common questions

Can babies or toddlers have soda?

No. Soda is carbonated sugar water, often acidic and sometimes caffeinated, and pediatric guidance is to keep sweetened drinks out of young children's diets. Water and milk are the drinks a baby or toddler needs.

Is a little sip of soda harmful?

One accidental sip is not an emergency, but soda should not be part of a young child's routine. The sugar and acid are hard on new teeth, colas add caffeine a small child should not have, and it builds a taste for sweet drinks that is hard to undo.

What about diet or zero-sugar soda?

Still no. Diet sodas replace sugar with low-calorie sweeteners, which are also not recommended for children under 5, and colas still carry caffeine and acid. There is no version of soda a baby or toddler needs.

My toddler wants fizzy drinks like everyone else. What can I offer?

Plain sparkling water with a few pieces of fruit gives the bubbles without sugar, acid, or caffeine. Keep it occasional, since carbonation can be a lot for a small stomach, and keep water and milk as the everyday drinks.
