Hey Maz - cool about Tank's hips. I was using the old flats which were too bulky in the middle and pushed out the hips and it was a big no no! But the new mcns are much trimmer in the middle so are OK. My oldest boy has CP (or closer enough) and there is also an hereditary hip condition thru the family so have had to be little careful. My Cp boy who had to wear sposies since his diangosis had has huge hip probs and surgeries anyway so prob made no difference.
