I have posted about this before, but I can't find the thread. Ds1 (8) feet turn in when he walks, especially his left.
Anyway, I finally got round to taking ds1 to the doctor. When she examined him at first she thought that his left hip was stiffer than his right, and this may be causing it. Then she ummed and ahhed and wasn't really sure if it is stiffer. She is thinking of referring him to orthopaedics, but has reffered him to physio first to see what they think.
She says that if there is nothing wrong with his hip then it is just loose hip joints causing his feet to turn in when he walks.
Anyone have any experience or information to share? Could it be a hip abnormality causing this?
