When can my baby eat shellfish? Shellfish can be a healthy part of your child's diet soon after she begins to eat solid food, usually when she's around 4 to 6 months. But if your baby has chronic eczema or a food allergy, talk to the doctor first before giving your baby shellfish.
After kids are on solid food, some parents have no problem letting them have raw fish. The generally recommended age at which kids can eat some kinds of raw fish varies from around age 2 1/2 to 3, all the way up to school age or age 6.
