Olive, My DD had this recently too. The small bumps and all over her torso. Scared the crap out of me but Dr Google images explained that it was hives LOL I thought back over her food and the only new thing was strawberries. I stopped giving them to her and they slowly went away, but she still has some so now I think she may be allergic to something different or as well as strawberries. I am going to give her them again in a few weeks and see if there is a reaction.

Hope it settles down for your little one.

I get big bumpy hives and have a few allergies, so it does not surprise me if poor DD has my health problems.
