Hip Displaysia

Hi Everyone
Shortly after my daughter Olivia started walking, I noticed she was tip toeing on her right side. She was 13 months old and both myself and my partner became concerned. We went to the doctors where Olivia was examined and were assured that her legs, feet and her hips were fine and that toe walking was common. Still not 100% certain we went to another doctor who checked Olivia and were told exactly the same thing. No x-rays were done as to their knowledge their didn't appear to be any problems. Still not sure we asked for a referal to a specialist. We had to wait a month or so but eventually got to see a specialist at the Childrens hospital, who at first glance ordered an x-ray.
To our disbelief the x-ray showed that Olivia Had Bilateral hip displaysia and that surgery was needed immediately to correct her right hip, six weeks in a hip spica and then all over again with the left. Then a Dennis Browne brace will have to be worn by Olivia for 12 months 23 hours a day. I can't believe it went undetected for so long. Olivia is 18 months old and her
first surgery is on the 18th Sept, we'd just like anyone that has gone through the same thing to be able to provide any inside info, tips to help our daughter, help us guide her through this difficult time. Thanks lucy
