Step 1: First tiny taste
Offer a small taste of well-cooked mashed or finely flaked halibut. Watch for concerning symptoms such as hives, swelling, vomiting, or breathing trouble, and seek urgent care if those occur.
Halibut is a fish and a priority allergen. Fish can be introduced with other complementary foods around 6 months. Offer well-cooked halibut as a single new food. If your baby has severe eczema or a prior immediate food allergy, talk with a clinician before introducing highly allergenic foods.
Remove all bones, skin, and fat. Cook halibut thoroughly until it is opaque and soft enough to mash easily with a fork, then mash, puree, or flake into small pieces. Never offer large firm chunks or bones. Always supervise eating.

If the first taste was tolerated, gradually offer a larger amount of the same preparation at a later feed.
If tolerated, keep this food in the diet routinely as part of complementary feeding.
Complementary foods are typically introduced around 6 months of age, when the baby shows developmental readiness (for example, sitting with support, good head control, and swallowing food rather than pushing it out). Introducing solids before 4 months is not recommended.
Once your baby is ready for solid foods (typically around 6 months), fish can be introduced with other complementary foods. There is no evidence that delaying common allergens such as fish prevents allergy.
Remove all fat, skin, and bones from fish before cooking. Cook until opaque and soft enough to mash easily with a fork, then mash, puree, or flake into small pieces. Always supervise eating.
Choose fish lower in mercury. Halibut is listed among FDA/EPA Good Choices. For young children, FDA/EPA advise choosing a variety of Best Choices more often. Avoid fish that are high in mercury, such as king mackerel, shark, swordfish, and bigeye tuna. This is educational guidance — follow your clinician’s advice if you have questions about your child’s diet.
