Well Natasha is up and running but there is a small problem. When she walks, runs and hopes she has what looks to be like stiff legs. SHe dose not use her knees to walk. I know they work she lays down prefectly fine. Her back legs are a little knobbey kneed. Her knees almost touch. Is there something that I can do. We do not want to splint her cause she is now moven around. We have to laugh at her when she comes running to mommy. It is little jumps all the way.
