I was changing lelands diaper this morning , brandy already left to run to the clinic to drop off some papers from the hospital, and he has a rash on his groin area well more up on his pelvis area, but then i looked and it goes up onto his belly, i lifted his shirt and its all over his back to and on his arms. His face looks ok. Its just like little red bumps or something. I was trying to get a hold of brandy or tanja but i couldnt to take him to the clinic with em. What could cause a rash like this?
