How to serve oatmeal by age

Oatmeal for 6 months+: smooth, thick oatmeal

6 months+

Smooth, thick oatmeal

Cook quick or rolled oats in water until very soft, then blend or mash until smooth. Thin with breast milk or formula if needed. Load a spoon and hand it to your baby, or let them scoop with their hands.

Size
A pre-loaded spoon of smooth oatmeal, thick enough to stay on the spoon.
Check before serving
Rub a little between your thumb and finger. It should feel soft and smooth, with no dry or chewy flakes.

US and UK advice differ here. The AAP suggests mashed food or soft pieces no larger than ½ inch; the NHS suggests soft finger-sized pieces your baby can hold in their fist. Both agree the food must squash easily.

Always have your child sit upright in a high chair or at the table, and stay with them the whole time they eat. Keep to the size and texture for their stage. Every baby develops on their own timeline.

How to prepare oatmeal

  1. 1

    Use plain oats with no added sugar or salt. Quick or rolled oats cook softest; steel-cut oats need longer cooking until very soft.

  2. 2

    Simmer the oats in water, stirring, a little longer than the package says, until soft and thick. Don't add salt.

  3. 3

    For young babies, blend or mash until smooth, and thin with breast milk or formula.

  4. 4

    Let it cool, stir well and check the temperature before serving.

  5. 5

    First time? Offer oats earlier in the day, so you can watch your baby for a few hours afterward. Oats can cause a delayed reaction: see when to call the doctor.

How much to offer

Start with a few teaspoons. Your baby decides how much to eat: stop when they turn away or close their mouth. Lots of licking, squashing and dropping is normal at first.

Common mistakes

Serving dry oats or granola

Dry oat flakes, granola and granola bars are hard and crumbly. The CDC lists granola bars as a choking hazard for young children. Cook oats until soft.

Adding sugar, honey or syrup

Babies don't need added sugar, and honey is never safe before 12 months. Stir in mashed fruit for sweetness instead.

Using flavored instant packets

Flavored packets can contain added sugar or salt. Check the label, or use plain oats.

Serving it too hot

Oatmeal holds heat, especially from the microwave. Stir it well and check the temperature before serving.

Questions parents ask

Can oatmeal be a choking hazard for babies?

Cooked oatmeal is a low choking risk. Dry oats, granola and granola bars are not: they're hard and crumbly, and the CDC lists granola bars as a choking hazard for young children. Serve oats cooked soft, and stay with your child during meals.

Can babies be allergic to oatmeal?

Oats are not one of the common food allergens. They don't contain wheat, but foods without wheat can pick up traces of it during manufacturing. If your child has a wheat allergy, the ACAAI advises avoiding products with warnings such as "made on shared equipment with wheat". These warnings are voluntary, so a label without one can still have traces: read the full label and ask your allergist which brands are safe. Oats are a common trigger of FPIES, a delayed reaction: see when to call the doctor.

Is oatmeal healthy for babies?

Plain cooked oatmeal provides some fiber, magnesium and zinc, and a little iron (about 0.9 mg per 100 g, cooked with water). Iron-fortified infant oat cereal has much more iron than plain oats.

Can babies eat oatmeal every day?

Yes, as part of a varied diet. Rotate in other grains too, and include iron-rich foods like meat, beans, lentils or iron-fortified cereal.

Can oatmeal help with constipation?

It can be part of the fix. Fiber from whole grains, fruits and vegetables helps keep stools soft. For babies under 1, the AAP suggests high-fiber foods such as peas, beans, prunes, pears and plums; for children over 1, it lists oatmeal among helpful whole grains. If you think your child is constipated, the NHS advises seeing your GP and getting help early. The AAP advises calling your pediatrician if constipation lasts more than a week after changing the diet.

Is oatmeal the same as infant oat cereal?

Not quite. Infant oat cereal is finely ground and fortified with iron, so it has far more iron than plain oats. Both are fine for babies; plain oats just need to be cooked soft.

If your baby refuses oatmeal

  • Many babies need 10 or more tries before they accept a new food. Keep offering it alongside foods they already like.
  • Try a different texture: smoother, thicker, or a little lumpier.
  • Stir in a fruit your baby already likes, such as mashed banana or pear cooked until soft.
  • Eat some yourself at the same meal. Babies copy what they see.

Never force or pressure your baby to eat. Some days they'll eat more, some days less, and that's normal.

Buying and storing oatmeal

  • Keep dry oats in a sealed container in a cool, dry place.
  • Cooked oatmeal keeps for 3 to 4 days in a covered container in the fridge.
  • Cooked oatmeal can be frozen in small portions for 3 to 4 months. Reheat only once, to 165°F (74°C), until steaming hot, stir, then let it cool before serving.
  • Throw away any food left out at room temperature for more than 2 hours (1 hour if it's hotter than 90°F / 32°C).

When to talk to your doctor

Contact your pediatrician, GP or health visitor if:

  • Your baby vomits a few hours after eating oats. This can be FPIES, a delayed type of food allergy that oats can trigger. If they vomited once or twice and seem alert and like themselves, call your pediatrician or GP. If they vomit again and again, or are pale, floppy, very sleepy or hard to wake, call your emergency number.
  • You notice mild signs of an allergic reaction after eating, such as a few hives or a little vomiting. See signs of a reaction.
  • You're worried about how much your baby eats, their growth, or they refuse most solid food for weeks.

Call 911999your local emergency number (such as 112 in Europe or 000 in Australia) now if your baby has trouble breathing, wheezing, can't cough or cry, has lips, mouth, tongue or throat that suddenly swell, or becomes pale, bluish, floppy or unresponsive. Also call if hives come with repeated vomiting.
