When Can I Give My Baby Fish and Shellfish?

While fish and shellfish are ​on the big eight list of food allergies, they tend to affect adults more than young children. There are also some fish you will want to avoid whether or not you have a history of allergies. This is because of the high mercury content.

Overview

You can give your child fish or shellfish at any time after they've gotten a good start with solid foods. The American Academy of Pediatrics used to advise parents to wait to give babies fish, but they've changed this stance, saying, "Within a few months of starting solid foods, your baby’s daily diet should include a variety of foods each day that may include...fish."

A study published in Nutrients even found that babies who start eating fish before the age of one have a lower risk of subsequently developing eczema, which is considered to be an allergy-related condition.

In many other countries where fish is more of a staple in the diet, babies are fed fish before other meats. These babies eat fish more often than our staples of chicken, pork and beef and they do just fine.

Be sure to check nutrition labels for fish ingredients and allergy statements that are required by the FDA. Whether or not you have a family history of allergy, the first time you introduce fish or shellfish, be sure to watch for the signs of an allergic reaction (hives, difficulty breathing or asthma symptoms, swelling of the mouth or throat, vomiting or diarrhea and loss of consciousness).

Mercury Content

The FDA recommends that you avoid giving young children shark, swordfish, king mackerel, and tilefish because of the high mercury levels. Pregnant and nursing women should also avoid these fish.

Good fish to start your baby on (after they have been eating solid foods for a couple of months) that are low in mercury include shrimp, canned light tuna (albacore is higher in mercury), salmon, pollock, and catfish. If your fish is locally caught, the FDA advises contacting local authorities first to see what's safe.
