Breakfast Cereal

Choking risk

Flaky and O-shaped cereals are moderate choking risk. They're round and firm when dry, and they need to soften before they're safe.

Let them sit in breast milk, formula, water or yogurt until they give way easily, and use plain whole milk only after 12 months.

Granola clusters and any cereal with whole nuts or seeds are the exceptions. They stay hard even once wet, so they wait until age 4.

Let flakes soften in the milk before serving, and hold the crunchy clusters for later years. See how to serve for age-by-age prep.

Allergens

Most breakfast cereals are made from wheat, a common food allergen.^[1]

Many boxes also carry milk, soy, almonds, or peanuts, so read the ingredients before pouring - and introduce each allergen on its own before offering a cereal that contains it. Corn, rice, and oat cereals are often wheat-free, but the label decides.^[2]

Start with a small amount and watch for a reaction.

Food safety

Sugar is the real issue in the cereal aisle. Children under 2 should have no added sugar at all, and most kid-marketed cereals are closer to dessert than breakfast - so under 2, stick to plain, low-sugar choices like unsweetened O's, plain wheat biscuits, or plain cornflakes.^[3][4]

Check sodium too - some plain-looking cereals run surprisingly salty.
