Hip Dysplaisa

My daughter was a C section breech baby. The doctors thought she had HD since day one. We’ve been through a fabric brace already and now she’s been put into a body cast for 3 months. We aren’t really getting any long term answers. If she’ll crawl, walk, if this can be fixed or if she’ll be in a wheelchair. I’m not even 100% sure how bad it is. I’ve seen the xrays and ultrasounds and every test they’ve done on her. But there’s no long term plan. Are there any parents out there that have been through this? Have any tips? How the babies/kids are now? Does this affect them their whole life?
