Ages are the usual introduction age from the source, not a target. Readiness matters more than the calendar — and a baby who hasn't started solids isn't ready for any of these foods yet.

How to serve mushrooms to a baby

Cut food for infants and young children into pieces no larger than one-half inch. Cut cylindrical foods (hot dogs, sausage, string cheese) into short thin strips — round pieces can get stuck in the airway. Cut small spherical foods (grapes, cherries, berries, tomatoes) into small pieces. Cook hard vegetables and fruit until they mash easily. Remove seeds, hard pits, skin and bones.

Is mushrooms a choking hazard?

Yes — Mushrooms are one of the foods the AAP and CDC name on their choking-hazard lists. The danger is almost always the shape rather than the food itself, which is why the serving form above is the whole answer. Cut everything to no larger than half an inch, cut cylindrical foods into short thin strips rather than rounds, and quarter anything round.

Allergies and mushrooms

Mushrooms are not one of the common allergens. Introduce it on its own anyway and wait 3 to 5 days before the next new food, so if your baby does react to something you know what it was.

Watch for diarrhea, rash, vomiting or hives after a new food. Call 911 for trouble breathing or swelling of the face, lips or tongue.

Worth knowing

Covered by the CDC's vegetable rule rather than named individually. Cooked mushroom is rubbery, so chop it very finely — a slice is the wrong shape for a baby.
