oat milk
Usually introduced around 12 months
Prep warning
Oat milk is not a complete substitute for breast milk or formula and should not be a main drink before 12 months. It is much lower in protein and fat than cow's milk, so it should not be a baby's only milk. Choose a fortified, unsweetened version and rely on the wider diet for protein, fat, and key nutrients.
How to serve by age
6-9 months
Oat milk is not a replacement for breast milk or formula at this age, but small amounts can be used in cooking. Stir a little fortified, unsweetened oat milk into oatmeal, mashed potato, or a vegetable purée to loosen the texture. It adds creaminess without becoming a main drink.
No cutting needed. Use small amounts in cooking, not as a drink.
9-12 months
Oat milk still should not replace breast milk or formula, but you can keep using it in cooked dishes. Mix fortified, unsweetened oat milk into porridge, pancakes, or creamy sauces. Choosing a calcium- and vitamin-fortified version makes it a more useful ingredient.
No cutting needed. Continue using small amounts in cooking rather than as a main drink.
12-18 months
From around a year, fortified unsweetened oat milk can be offered as a drink in an open or straw cup if cow's milk is not used. It is naturally low in protein and fat compared with cow's milk, so make sure the rest of the diet provides plenty of both, and choose a version fortified with calcium and vitamins.
No cutting needed. Serve in an open or straw cup, not a bottle.
