Walnut is a tree nut, one of the major allergens. Introduce it on its own, early in the day, in a small amount, and wait a few days before trying another new allergen so any reaction is easy to spot. Watch for rash, hives, swelling, vomiting, or diarrhea, and seek emergency care for any trouble breathing.
Whole walnuts and pieces of walnut are a serious choking hazard and should not be given before about age 5. Even a thick blob of walnut butter can be risky, so always thin it. The only safe forms for a baby or toddler are smooth thinned butter and finely ground walnut mixed into food.
Walnuts are a tree nut, one of the common allergens, and best introduced early in a safe form. Use smooth walnut butter thinned with breast milk, formula, or your baby's usual food to a lick-off consistency, or finely ground walnut flour stirred into porridge or purée. Never offer a whole walnut, a piece of one, or a thick blob of butter.
Smooth thinned walnut butter or fine walnut flour only. No whole or chopped nuts.
Keep offering walnut only as smooth thinned butter or fine flour, mixed into food. The texture can be a little thicker now, but it must still have no pieces. Whole and chopped nuts stay off the menu because they are a serious choking hazard at this age.
Smooth thinned butter or fine flour, still no pieces.
Walnut butter spread thinly on a soft toast strip, ground walnut baked into muffins or pancakes, or fine walnut flour stirred into food all work well. Still no whole or coarsely chopped nuts: whole and chopped nuts remain a choking hazard until about age 5.
Thinly spread butter, ground walnut, or fine flour. No whole or chopped nuts.
Ground walnut, walnut butter on a soft carrier, or finely crushed walnut baked into foods stay the safe forms. The one age-specific change comes around age 5, when whole nuts can be introduced once your child chews and sits to eat reliably. Before then, keep nuts ground, crushed fine, or as smooth butter.
Ground, finely crushed, or smooth butter until about age 5, then whole nuts.
