My ds has had various reactions to various foods and chemicals reacting with either gastro symptoms..vomiting, diarhoea, bloating or excema which has been mostly contact related eg, mouth, face and hands flare up when it is an offending food, body reacts when it is a soap powder etc. We introduced banana for the first time this week and his tummy is now quite spotty. There is a cluster of spots around his naval which are red and close together, and around 8-10 spread around the rest of his tummy some which look to have a small head on them. He has been really really scratchy lately, we will take out the banana for a while and retry but what do ppl think is it a reaction or something else?
