fused labia ... estrogen cream?

Tiffany • Wife 💍 Girl mom 💖 Boy mom 💙 Best of both worlds💕
Hey moms, my daughter has a fused labia the pediatrician said to use aquaphor and if it didn't improve we'd start estrogen cream, but wanted to hold off as long as possible bc of the side effects. Well it's not improving it's actually getting worse so we are starting the estrogen cream.
    Anyone have any experience with this? Did it work? Where there any side effects? 
   Or has anyone had to deal with the surgery to fix it? How was that?
