How to serve tuna steaks by age
Shapes and textures change as your baby’s grasp and chewing grow.

Skip albacore, yellowfin and bigeye tuna steaks for now. Offer canned light or skipjack tuna mashed smooth with avocado, yogurt or potato on a spoon, or low-mercury fish like salmon and cod blended into a puree.

7–8 months
Keep skipping tuna steaks. Canned light or skipjack tuna mashed more roughly with avocado or potato, or soft flakes of salmon and cod, are good options at this age.

9–12 months
Keep choosing low-mercury fish. Light tuna cakes, flaked salmon or cod in pasta are good options at this age.

12 months +
From about 3 years, offer small portions of fully cooked albacore or yellowfin tuna steak, cooked until opaque all the way through and flaked or cut into thin strips. Keep it to an occasional serving and continue to avoid bigeye tuna.
Why it’s good
Tuna steaks are rich in protein, omega-3 fats, vitamin B12, vitamin D, selenium, niacin and iron. However, large tuna species build up more mercury, which can affect a young child's developing brain. Lower-mercury fish give similar nutrients with less risk.
