Whole Milk for Babies: When It Becomes a Drink, and Pasteurized Only
Whole cow's milk becomes a main drink after the first birthday, not before. Choose pasteurized, and know why raw milk is a real risk.

When can babies eat whole milk?
There are two things to know about cow's milk. First, as a main drink it waits until the first birthday, because before then it can crowd out breast milk or formula and is hard on a young system. Small amounts cooked into food, and yogurt and cheese, are fine earlier. Second, it must be pasteurized, as the warning explains. After a year, offer whole (full-fat) pasteurized milk in a cup.

Is whole milk safe? Choking & prep
Two rules: pasteurized only (see the warning), and not as a main drink before 12 months. Offer it in a cup rather than a bottle, and choose full-fat for under-twos, who need the fat.
Nutrition
Whole cow's milk provides calcium, protein, fat, and vitamin D. Full-fat is recommended for children under two, whose brains and bodies use the fat.

Frequently asked questions
When can babies have cow's milk as a drink?
As a main drink, from around 12 months. Before then, breast milk or formula should be the main drink, though small amounts of milk cooked into food, and yogurt and cheese, are fine earlier.
Why does milk have to be pasteurized?
Raw (unpasteurized) milk can carry bacteria like listeria and E. coli that are dangerous for babies. Pasteurization kills them without meaningfully changing the nutrition.
Whole milk or low-fat for a toddler?
Whole (full-fat) milk for children under two, who need the fat for growth and brain development, unless your pediatrician advises otherwise.
Can babies have milk in food before 12 months?
Yes, small amounts of pasteurized milk cooked into food, and yogurt and cheese, are fine from around 6 months. It is milk as the main drink that waits until a year.
