When can babies have oat cereal?
Can babies have oat cereal?
Babies can have iron-fortified infant oat cereal from about 6 months, mixed with breast milk, formula or water. Oat cereal is a great everyday grain because it is fortified with iron and lower in arsenic than rice cereal. Oats are not a Top 9 allergen, but some brands are processed with wheat.
How to serve oat cereal by age
Shapes and textures change as your baby’s grasp and chewing grow.
6 months
Mix iron-fortified infant oat cereal with breast milk, formula or water until smooth, then offer it on a spoon or pre-loaded spoon. Stir in smooth fruit or vegetable puree, or a little thinned peanut butter, for flavor and allergen practice.
7–8 months
Make oat cereal thicker and stir in fork-mashed fruit for a lumpier texture. It also works as a coating to make slippery soft foods like ripe banana or avocado pieces easier to grip.
9–12 months
Make it thicker and use it in baby pancakes, oat fingers or muffins your baby can hold. Oat cereal also works as a coating to make slippery foods like banana or avocado easier to grip.
12 months +
Toddlers can eat oat cereal mixed into yogurt, oatmeal or baked goods for an iron boost. Most toddlers are ready for regular oatmeal, so infant cereal becomes optional.
Why it’s good
Infant oat cereal is fortified with iron and often zinc and B vitamins, nutrients babies need more of from 6 months. Oats also bring fiber, which helps keep stools soft. Serve it with vitamin C rich fruit like strawberries or mango to help absorb the iron.
Safety notes
- Use iron-fortified infant oat cereal made for babies, not adult instant oatmeal packets, which can have added sugar and salt.
- Do not put oat cereal in a bottle unless your pediatrician advises it.
- Check the label for wheat or other allergens if your baby has a known allergy, as some oat cereals are processed with wheat or contain other grains.
- Mix only what your baby will eat, and throw away leftovers that touched a used spoon.
A low-allergy food, still worth watching
Oats are not one of the Top 9 allergens, but oats are often processed in facilities with wheat, so check the label if your baby has a wheat allergy. Oats are also a known FPIES trigger in a small number of babies, which causes repeated vomiting a few hours after eating.
