Dairy for babies: yogurt, cheese & when to introduce milk
Dairy is one of the nine major allergens — and one of the most confusing, because yogurt and cheese are fine early but cow's milk as a drink waits. Here's the simple version, and how to introduce dairy safely.
Babies can have yogurt and cheese around 6 months, but cow's milk as a main drink waits until 12 months. Dairy is a common allergen, so introduce it on its own and watch for a reaction.

Plain, unsweetened whole-milk yogurt is a great first dairy, usually around 6 months, once your baby is eating solids. It's smooth, easy to spoon, and a simple way to introduce the milk allergen. Skip added sugar and flavored varieties, and never add honey before 12 months. Greek or regular both work — go for full-fat, since babies need the fat.
02When can babies have cheese?
Small amounts of pasteurized cheese are fine around 6 months, served in soft, age-appropriate pieces or grated into food. Choose lower-sodium options (a lot of cheese is salty) and pasteurized only.
Large cubes and stringy cheese (like string cheese) are choking hazards. Grate hard cheese, or cut soft cheese into thin, small pieces.
03When can babies have cow's milk?
Whole cow's milk as a main drink is recommended from 12 months. Before then, dairy in foods — yogurt, cheese, a splash cooked into a recipe — is fine. The reason for waiting is that cow's milk as a replacement for breast milk or formula doesn't give babies under one the iron and nutrition they need, not that the allergen itself is off-limits.
04Milk allergy vs lactose intolerance
These get mixed up, but they're different. A milk allergy is an immune reaction to milk protein and can cause hives, swelling, vomiting, or — rarely — breathing trouble. Lactose intolerance is digestive (gas, bloating, loose stools) and is uncommon in babies.
- Mild allergy signs: hives, redness around the mouth, mild swelling, vomiting. Stop and call your pediatrician.
- Severe (call 911): trouble breathing, swelling of the lips/tongue/face, repeated vomiting, or a pale, floppy baby.

Once yogurt or cheese goes well, keep dairy in your baby's diet regularly — tolerance is maintained by repeated exposure. Working through all nine allergens? Our free allergen introduction schedule keeps dairy, egg, peanut, and the rest organized.
