Prep warning
Pistachios are a tree nut, one of the major allergens. Introduce a small amount on its own, early in the day, and wait before adding another new allergen so any reaction is easy to spot.
Choking notes
Whole and chopped pistachios are a high choking risk and are generally kept away from children until about age 5. Always remove the shells, and thin pistachio butter to a runny consistency before mixing it into other food, since a thick spoonful can also be a hazard.
How to serve by age
6-9 months
Serve pistachios only as a smooth pistachio butter thinned with breast milk, formula, or water to a runny, lick-off consistency, or finely ground and stirred into purée, yogurt, or porridge. As a tree nut, it is a common allergen, so offer a small amount on its own early in the day and watch for a reaction.
No pieces at all, and remove every shell first. Whole or chopped pistachios are a choking hazard well past this age; serve only as thinned butter or fine flour mixed into food, never in a blob.
9-12 months
Keep offering thinned pistachio butter or fine ground pistachio, blended into mashes, yogurt, or porridge. It can be a little thicker now but should still smear easily. Keep allergen exposures regular once tolerated.
Still no whole or chopped pistachios. The choking rule for tree nuts does not change yet; keep it as thinned butter or fine flour only.
12-18 months
Ground pistachios or a thin layer of pistachio butter on a soft carrier like toast work well, and ground pistachios can be baked into muffins or stirred through yogurt. Keep any spread thin.
Whole and coarsely chopped pistachios remain off the menu. If you want texture, grind or flake them very finely; never serve whole nuts.
2 years and up
Crushed, finely flaked, or ground pistachios and thin pistachio butter on soft food stay the safe forms. The one age-specific change is that whole nuts are generally not offered until about age 5.
Keep to crushed or flaked only. Whole pistachios are commonly held back until around age 5 because of the choking risk.
