Grounded in: the 2019 Healthy Drinks for Kids consensus (AAP, American Academy of Pediatric Dentistry, Academy of Nutrition and Dietetics and American Heart Association), AAP HealthyChildren guidance on milk for toddlers, the Dietary Guidelines for Americans 2020-2025, and CDC guidance on raw milk.

## TLDR

- From 12 months, plain whole cow's milk can replace formula; 16-24 oz a day is plenty. Most can switch to low-fat at 2.
- Unsweetened fortified soy milk is the closest plant match; oat, almond and coconut are too low in protein as the main milk.
- Avoid raw milk. Dairy-free toddlers can thrive with a plan for protein, calcium, vitamin D, B12 and iron.

## The basics

- From 12 months, plain pasteurized whole cow's milk can replace formula. See the cups and milk
  guide for moving from bottle to cup.
- About 16-24 oz (475-710 mL) a day is plenty. More can crowd out food, and lead to low iron and
  constipation.
- From age 2, most children can switch to low-fat (1%) or skim milk. Your pediatrician may suggest
  this earlier or later based on growth and family history.
- Toddler or "transition" formulas aren't needed and cost more.
- Breastfeeding can continue. A toddler who nurses several times a day doesn't need cow's milk,
  but still needs calcium and vitamin D from foods like yogurt, cheese, tofu and fortified foods.

## Making the switch

- Go straight to cow's milk, or mix it with formula or breast milk for a week or two if your child
  resists.
- Cold, room-temperature or warm are all fine.
- Serve milk with meals and water between meals.

## Plant milks compared

- **Fortified soy milk (unsweetened):** the only plant milk the US consensus treats as a near-match
  for cow's milk in protein and nutrients.
- **Pea-protein milks:** some are made with protein close to cow's milk and fortified; there's less
  research on them, so check labels and ask your pediatrician.
- **Oat, almond, coconut, cashew and hemp:** low in protein and often in fat and calories. Fine in
  cooking or cereal, but not as the main milk without a plan.
- **Rice milk:** low in protein and can contain arsenic. Not recommended as a toddler's main drink.

Whichever you choose, pick unsweetened and fortified with calcium and vitamin D, and offer other
protein and fat sources.

## Families who skip dairy

For milk allergy, veganism, religious or cultural practice, or simple preference, a toddler can
thrive without cow's milk with some planning. Focus on protein (beans, lentils, tofu, eggs or meat
if you eat them), calcium, vitamin D, vitamin B12, iron and healthy fats. A pediatric dietitian
can help. See the vitamins and supplements guide.

## Lactose intolerance and allergy

- Lactose intolerance is uncommon in toddlers. Lactose-free cow's milk has the same nutrients.
- Milk allergy can cause hives, vomiting, eczema flares or blood in stool. Talk to your pediatrician
  before switching milks.

## Milks to avoid

- Raw (unpasteurized) milk from any animal. It can carry dangerous germs.
- Unmodified goat or sheep milk as the main drink, unless pasteurized, fortified and agreed with
  your pediatrician.
- Flavored or sweetened milks, and condensed or evaporated milk as a drink.

## When to check in

- Mention it at the next checkup if your toddler drinks much more than 24 oz (710 mL) a day, eats
  little, or seems pale and tired.
- Ask before using a plant milk as the main drink, or if constipation follows the switch.
- If your child has swelling of the face or lips or trouble breathing after milk, call 911.
