NEVER BEFORE

12 months

CDCCDCAAP

Watch for Common allergen (cow's milk). Introduce it early rather than delaying, on its own, then keep it in the diet regularly.
Emergency? Call 911 now if your baby is choking and cannot cry or cough, is struggling to breathe, or has swelling of the face, lips or tongue, or widespread hives after eating. Do not wait to see whether it settles. This tool is a reference, not medical advice.

Is cow's milk (as a drink) a choking hazard?

Cut it to no larger than half an inch, keep your baby sitting up in a high chair, keep mealtimes calm, and watch them the whole time they are eating.

Allergies and cow's milk (as a drink)

Cow's milk (as a drink) is one of the common allergens (cow's milk). The current AAP guidance is to introduce it EARLY rather than delay it: newer research found no benefit to waiting, and for peanut, waiting can increase the chance of an allergy. Offer a small amount in an infant-safe form, watch for a reaction, and then keep it in the diet regularly. If your baby has severe or persistent eczema, or has already had an immediate allergic reaction to a food, especially egg, talk to your pediatrician first about how and when to introduce it.

Watch for diarrhea, rash, vomiting or hives after a new food. Call 911 for trouble breathing or swelling of the face, lips or tongue.
