Re: extra crease in babys thigh?
My DD had this at her 2 month check up with the doctor. The pediatrician asked if she was breech and when I told her she was, she said she should have a hip ultrasound. Sometimes if either baby was breech or in a funny position while in utero, I guess it can deform one or both of the hips. But my DD had the ultrasound and she was normal. But I bet that's why it was noted. I don't know if this is an issue if your child wasn't breech, but I'd ask your pediatrician just to be safe.
