We took DD's old pod off tonight, granted it stayed on an extra day. We put a new pod on last night, but didn't get around to removing the old one till this evening. We noticed about a week ago when we took off band aids it looked irritated underneath. Then we took off this pod and it is all red and blistered and awful looking. DD didn't mention it hurting or anything so it was a real surprise to see it look so raw. So, what can we use as a barrier underneath her pod?
