my 3 week old has a rash that is peelingher inner thighs along where her diaper meets her legs she is also red all over her diaper area. she has been only breast feed since 4 days old, i haven't eaten anything new, we have used pampers since birth, she is changed quite often, could it be a reaction to something? we have been using desitin but today she seems to cry either right before or when she urinates hard to tell. she doesn't have a fever...any thoughts? should i get her in to the dr before the wknd???
