How old is she again? My daughter when she was an infant had presented with a rash that came and went before my eyes! They were little hives. I thought they were chicken pocks. Here the ped. told us that in infants they react to infections in different ways. She did have an UTI . So that is what I looked for when she was an infant. As she got older I looked for a fever that was unexplained. And earlier this year she is now telling me when her pee-pee hurts because she is potty trained. I hope this helps and I pray this is not the begining of more UTI to come. Push the water! Push plain cranberry juice (no apple in it)! If she is potty training, make her void every two hours faithfully. Good luck and keep us updated! I hope she is feeling better soon.
