my 4 year old daughter has a mild skin rash on her face (primarily nose and forehead), a little on her neck and on her stomach. They are just bumps, not red or irritated looking, and shes not itching or bothered by them at all though. I did just notice, though, that she has 2 canker sores on the inside of her bottom lip also. What do you think this could be coming from and does she need to be seen? Thanks
