Is diaper rash usually itchy? Lately my baby will scratch her diaper area, especially when i take the diaper off, Because she has such sharp nails I dont like her scracth herself at all. I dont know if she is doing this out of habit or if she is really itchy. becuase she also rubs her face when she is tired and pulls her hair when she is scared or startled. She only does this with her left hand. Have your LO's ever done this?
