Shellfish for babies
Shellfish is a major allergen and one of the more common lifelong ones, so it is worth introducing early but thoughtfully. Here is when to start, why it is not the same as fish, and how to serve it safely.
When to introduce it
From around 6 months. As with other allergens, delaying shellfish is not recommended for most babies, early, regular exposure is the current approach. If there is a strong family history of shellfish allergy, or your baby has severe eczema or another food allergy, check with your pediatrician or an allergist first. See introducing allergens.
Not the same as fish
Fish and shellfish are separate allergens, being fine with salmon says nothing about shrimp. Shellfish itself divides into crustaceans (shrimp, crab, lobster) and mollusks (clams, mussels, oysters, scallops), with crustaceans the more common trigger. Introduce and watch each on its own. See fish for babies.
How to serve it safely
Two rules: cook it thoroughly (never raw, to avoid foodborne illness) and manage the texture. Shellfish can be rubbery and chewy, a choking risk, so remove all shell and finely chop or mince cooked shrimp, or blend it into a purée. Keep it plain and unsalted, and start with a small amount.
Introduce thoughtfully, and watch
Because shellfish reactions can be significant, give a small first taste earlier in the day and keep an eye out over the next few hours and days. Know the signs: signs of a food allergy. Logging the first try in Yummy Yucky starts the 3-day watch for you.

Frequently asked questions
When can babies have shellfish?
From around 6 months, once solids are underway. Shellfish is a major allergen, and current guidance is to introduce allergens early rather than delay them. If there is a strong family history of shellfish allergy, or your baby has severe eczema or another food allergy, talk to your pediatrician or an allergist about how to introduce it.
Is shellfish the same allergen as fish?
No, they are completely separate. Fish (like salmon and cod) and shellfish are different allergens, so tolerating one tells you nothing about the other, introduce and watch each on its own. Shellfish itself splits into crustaceans (shrimp, crab, lobster) and mollusks (clams, mussels, oysters, scallops); crustaceans are the more common trigger.
How do I prepare shellfish for a baby?
Cook it thoroughly, never raw, remove all shell, and chop it small. Shellfish can be rubbery, which is a choking texture, so finely chop or mince cooked shrimp, or blend it into a purée. Start with a small amount and keep it plain and unsalted.
Why is shellfish allergy a bigger deal?
Shellfish allergy is one of the more common lifelong food allergies and reactions can be significant, so it is worth introducing thoughtfully: a small first amount, earlier in the day, with a careful watch over the next few hours and days. That said, delaying it is not recommended for most babies.
