DD1 was dx at about 4 or 5 months. She was checked by 2 midwives, GP's and MCHN's and all said she seemed fine. But her legs were literally uneven, but she had no click so I guess nobody was concerned. Turned out her hip was a mm away from being completely dislocated. So good luck at the US. It was a difficult having it happen later in the game, but we managed okay.
