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.
Even if you've never had any symptoms of a shellfish allergy before, you can suddenly develop allergies to shellfish as an adult. In fact, 60 percent of people with shellfish allergies develop them later in life, even if they've been eating shellfish since they were young.Your chance of developing a shellfish allergy increases to 30 or 40 percent if one of your parents has a food allergy, and up to 75 percent if both of your parents are allergic.Once you have a shellfish allergy, you're most likely stuck with it for life.our chance of developing a shellfish allergy increases to 30 or 40 percent if one of your parents has a food allergy, and up to 75 percent if both of your parents are allergic.
