My 17mo is not walking or standing independently yet. He tip toes on his left foot constantly when walking with his walker and standing up at something. Right foot is flat. I have seen a physio and gp who say there’s nothing obvious wrong with him musculoskeletal wise. The physio gave me some exercises to do which he’s not tolerating very well and doesn’t seem to be making much difference either. My question is has anyone else experienced this and is it just a case of waiting for them to grow out of it?
