Hi - my 2 1/2 year old daughter has a red blotchy rash all over her body. It seems to flare up in/after a bath and doesn't seem to be itchy. The shape of each individual rash varies, but they are all more red near the outer boundaries and get lighter to white on the inside. It is mostly around her shoulders, stomach and hip/upper leg area. We've tried no bubble bath but have used the same soap to clean her with and it doesn't seem to make a difference. If we go swimming, it also seems to flare up, although not as much as after/during a bath. Any thoughts on what this could be? Many thanks.
