Thanks for checking in, I've been mean to come in and update you guys. We had the scan on Tuesday which was ok. I was a little bit concerned because the technician had said that the left hip was immature (the socket had measured at 55, when it should be 60 like the right one). She did tell me that it wasn't dysplacia though, but wouldn't offer any real explanation about what it meant for it to be immature. But we went to the GP yesterday to get the results and she told me it was nothing to worry about and that his hips are fine, so that was a big relief!
