Hello, two-year-old babies can add seafood in moderation, but they must start from a small amount. At the same time, observe whether the baby is allergic, and avoid contact with allergic seafood in the future. Seafood food is easy to cause allergies, but this does not mean that any seafood food will cause allergies. For a child, some seafood can cause allergies, and some seafood may not cause allergies. If you are allergic to hairtail, don't eat hairtail next time, but yellow croaker can still be eaten. If there are too many restrictions on children's food, it will affect their overall intake of nutrients. Although seafood is rich in nutrition, it is not advisable to eat more. Affected by marine pollution, seafood often contains toxins and harmful substances. Excessive consumption can easily lead to spleen and stomach damage and cause gastrointestinal diseases. If eaten improperly, food poisoning will occur in severe cases. So pay attention to the right amount of seafood, usually once a week.
