Animal foods generally contain much higher zinc than plant foods and are more easily absorbed.

Oysters have the highest zinc content, and other shellfish are also very rich in zinc. Mom can stew some seafood soup for the older baby, such as scallops, conchs and mussels.

Animal livers also contain high levels of zinc. Chopped duck liver and chicken liver, plus egg yolk, are more suitable for younger babies.
