Although hairy crabs are rich in nutrition, they are indeed a kind of food allergic to skin. Before giving your baby crabs for the first time, it is very possible to eliminate your baby's allergies to crabs. You can take a little crab roe for the baby to taste. If the baby has allergic symptoms after 30 minutes, you can let the baby eat it again. It must be noted that children must be given fresh and cooked hairy crabs, and there is no need for children to eat crab hearts and stomachs.
