my dd is 9 mos, and i remember at her 6 month appointment the ped said that her vagina was slightly closed but it was nothing to be concerned about it will open up on its own and that it is common with girls. Shes went to her 9 mo appointment today and he mentioned it again. Ive never heard of this before? he said once the females start to produce their own estrogen it starts to open up. in extreme cases the baby is perscribed estrogen cream to rub onto the vag to open it up. Has this happened to anyone else before?
