Anyone else have a child constantly rub their legs together? 2yo girl.

So ever since my daughter was about 6-8 months old she has always crossed her legs. It was cute at first like, look how ladylike, hahaha. But ever since she could walk she began crossing her legs standing in the fashion you would if you had to pee really bad. Leaning to one side very hard. She does it standing, sitting, and laying down. She is very serious and quiet when she does it. We ask her if something is wrong but she can't say many words yet so she can't really tell us if she is in pain.​We took her to a doctor a year ago and he said there was some hip dysplasia and we took MRI and X-rays etc. Went back after a few months of physical therapy and inserts for her shoes. He said the hip socket is developing well and she won't need to be in a sling or anything like that. She walks and runs fine. And she'll do this non-stop all day for a few days then not do it for weeks. We don't know whats going on. Doctors don't know. I feel like it's not normal.​Could it be something with her privates? Constipation? Hips? Self soothing? Has anyone else had a child do this?​Help? via /r/Parenting https://ift.tt/2G4f2Ay
