When can babies have cashew? Is cashew a common allergen? How to serve it safely Keep it in rotation FAQ

01When can babies have cashew?

Like other common allergens, cashew can usually be introduced around 6 months, once your baby is eating solids and showing readiness signs — sitting with support, steady head control, and interest in food. If your baby has severe eczema or an existing food allergy, check with your pediatrician about timing first.

Already started peanut?

Cashew is a natural next step. See the full order of operations in our guide to introducing allergens.

02Is cashew a common allergen?

Yes — cashew is a tree nut and a major allergen. Cashew is one of the tree nuts more frequently associated with significant allergic reactions in children, so offer the first taste at home, earlier in the day, and watch closely.

Cross-reactivity note

Cashew and pistachio belong to the same botanical family and often cross-react — a child allergic to one is frequently sensitive to the other. (There can also be links with mango and pink peppercorn.) Introduce cashew and pistachio separately.

03How to serve cashew to your baby safely

Choking hazard

Never give a baby whole cashew or thick globs of nut butter — both can block a small airway. Always thin nut butter or grind nuts finely into food.

  1. Use a smooth cashew butter (or very finely ground cashew) — no pieces.
  2. Thin it with warm water, breast milk, formula, or a familiar purée until smooth and easy to swallow.
  3. Offer a small taste on the tip of a spoon, then wait ~10 minutes before offering more.
  4. Watch for about 2 hours, earlier in the day, when your baby is healthy and you're at home.

04Keep it in rotation

Once cashew goes well, keep it in your baby's diet regularly — about twice a week. Tolerance is maintained by repeated exposure, not a single taste. Juggling seven separate nuts is exactly why we built Tiny Acorn: one smooth blend that keeps all seven in the rotation. Join the waitlist →
