Oyster
Overview
Oyster is a typical complementary protein around 6 months when your baby shows readiness for solids. Offer well-cooked mashed oyster as a single new food.
Preparation
Remove shells. Cook oysters thoroughly until they are soft enough to mash easily with a fork, then mash, puree, or flake into small pieces. Do not offer raw oysters to infants. Never offer large firm pieces. Always supervise eating.

FAQ
When are babies usually ready for solid foods?
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.
Do I need to introduce foods in a certain order?
For most children, there is no required order for first foods. Fruits, vegetables, meats and other proteins, and other food groups can all be part of complementary feeding around 6 months.
How should I prepare oysters for a baby?
Remove shells. Cook oysters thoroughly until they are soft enough to mash easily with a fork, then mash, puree, or flake into small pieces. Do not offer raw oysters to infants. Always supervise eating.
Is oyster a lower-mercury seafood?
Yes. Choose seafood lower in mercury. Oyster is listed among FDA/EPA Best Choices. 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.
