Hi Belfie, There is definatley a chance it could be something significant the requires treatment, but then there also the possibility it is nothing to worry about. My daughter had uneven creases, another indicator of hip issues and had further investigation with scans, turned out to be nothing at all. Another 2 babies in MG had hips investigated and all was fine too.
The health system are pretty ontop of hip issues in youngsters because they are generally easier to treat when picked up early. Mf girlfriends DD needed to wear a removable hip brace for 6 months, but this meant she didn't require an operation later in life. (She is 100% totally fine now, caught her first wave on a surfboard age 3 on the weekend. )
So i guess my point is sometimes they are over the top with hip issues, but it is warranted as issues are best picked up early. Best of luck on Monday, hope it is nothing. Of course it is natural to worry but try not too!
