Allergy to threadfin

It depends on the severity of the allergic reaction. And sometimes the 2nd time baby gets given the same food, the reaction can be more severe, because they’ve already built up some antibodies from the first exposure. So if you’re cousin’s not entirely sure how to reintroduce the food, perhaps consulting a PD first would be wise? For reintroduction, it needs to be given in a really small amount without other new ingredients, watch for reactions, and then gradually build up over days to weeks. And the child does run the risk of anaphylaxis, which can be dangerous.. so seeking professional advice would be good before trying again.
