My daughter is a just a little over two months and recently she has been getting light green blisters around her diaper area, On her thighs and now she has one on her butt. They look like normal blisters except they are like a yellow green color. They haven't been hurting he but now they are coming more frequently. Last night as I was bathing her I notice around her thighs and lady bits were swollen and she was in pain when sitting a certain way. I am waiting for the doctor to call me back...What could this be??
