When can babies have crab?
From 6 months (corrected age), in the age-right form below.
- Complete protein that arrives naturally soft and shredded
- One of the richest everyday sources of zinc for growth and immune function
- A naturally low-mercury seafood with vitamin B12
How do I serve it at each age?
Safe form at 6–8 months
Fully cooked crabmeat picked over piece by piece for shell and cartilage fragments, shredded to soft threads, moistened with a little water or cooking liquid, and folded into a familiar puree or mash.
Pass/fail test: Spread the shreds thin on a plate and drag a fingertip through every bit — you should feel only soft, moist threads, never a hard or papery edge, and each shred should flatten under a light press.
Why this form: Cooked crab is naturally tender enough for bare gums, so the real work is the fragment check — a stray sliver of shell is the only hard thing in an otherwise perfect early texture.
How to prepare
- Steam or buy fully cooked crab, pick the meat, then spread it thin and run fingertips through every shred to catch shell and cartilage fragments.
- Shred to soft threads, stir in a spoonful of water or cooking liquid so the meat clumps softly, and fold into a familiar mash.
- Mix into or serve alongside familiar foods, never another new food.
- First time: serve early in the day, a small amount, and watch for 2 hours.
Common mistakes
- Trusting 'picked' crabmeat straight from the tub — small shell fragments routinely survive commercial picking.
- Reaching for imitation crab, which is a salty processed blend that contains fish paste rather than crab.
- Introducing crab at dinner, so any delayed reaction lands overnight.
How much?
A teaspoon or two of moist shreds folded into a familiar mash — a taste-size first serve that grows with tolerance.
About twice a week once tolerated, to keep the shellfish exposure steady.
Amounts are starting points, not targets — watch the baby, not the numbers.
How do I get the texture right?
- Do the fragment check in bright light with the meat spread thin — shell slivers are the same color as the meat and hide inside clumps.
- Fresh-picked or refrigerated pasteurized lump crab is the easiest starting point; give canned crab a brief rinse to shed some of its salt.
- A spoonful of mashed avocado binds dry crab shreds into clumps a baby can actually pick up.
- Freeze checked, moistened crab in ice-cube portions so keeping shellfish in the rotation never requires picking a whole crab again.
Is crab a choking hazard?
Low risk in the forms above — shape and texture do the safety work. Any food can be a hazard served the wrong way, so match the form to your baby’s age.
Is crab a common allergen?
Common allergen: Shellfish
Yes — introduce it early in the day, alongside familiar foods, and watch for 2 hours. See the Shellfish introduction program →
Anything to watch for?
Imitation crab (surimi) is a salty processed product made from fish paste — it carries far more sodium and doesn't provide the shellfish exposure real crab does.
Canned and pasteurized crab can be briny — a quick rinse in a sieve brings the salt down.
