How much shrimp should a child be allowed to eat each day and what are the effects if a child eats too much?

Smart mom! Shrimp or Prawns can cause an allergic reaction if too many are eaten and it just happened to my husband last year. If just a few are eaten in a two day period there should be no problem. 8 - 10 small shrimp twice a week is just fine for your son and 5 - 6 prawns (larger) cooked is fine as well, but no more!
