I have never in my life been so happy to say that I was wrong!!!
Juno's doctor was able to get us in this week instead of in two weeks (possibly because I called and begged....) and so we went in yesterday morning at 8 am for an x-ray.
Woohoo! Hip is still in the socket!!
I was surprised but absolutely thrilled to get that news.
Juno's hip is firmly in place, her socket is deepening nicely, and her growth plates are starting to catch up to the other side. Doc said the length discrepency I was noticing was below the knee and probably due to immature growth plates, but not significant enough to be a cause for concern. Her HD hip has great mobility and he told me not to worry about anything. We don't even have to go back until her birthday!!!
Thank you, thank you for all the prayers and good thoughts!
