We had hip problems with my DD but we in NZ-in the Waikato they scan all breech babies and it showed up in the scan at 2 months old. As Ariel said the earlier the better, while the hip is still cartilage. For my DD we had a fabric brace for a couple of months, 23 hours a day-was horrid but has fixed the problem. Really good to get checked before she starts walking, here's hoping there is no problem as plunket do refer lots of kids to get checked and only some actually have problems. My DD had a few risk factors-she was first born (less room), a girl (for some reason girls hips are more easily put out), breech (so squashed in a bad position) and there is a family history- I only just found out about this-she had a great aunt who had problems with both hips and it was not picked up until it was too late.

Good luck and fx for no probs
