DD has a few allergies which have resulted in hives in the past. We are just home from a walk where she was rolling down hills and playing in the grass. We had been home for about an hour when she started complaining of her skin feeling very itchy. She has a rash which at first I thought was just skin irritation from her rolling on the grass but there is a small amount on her tummy which should have been covered by her dress. Although, some grass could have sort of travelled up the dress I suppose. This clearly isn't hives but I've given her some piriton just to be on the safe side. I'm just feeling a little worried because some of her previous reactions have been quite severe. Any advice greatly appreciated.
