DS is 16 months and has been walking properly since 11 months. The last few weeks he's been either walking on his tiptoes or walking with bent legs, which looks like he's about to collapse! I'm finding it a bit disconcerting
I have googled and one of the top results is that walking on tiptoes is a sign of autism. IMO he doesn't show any other signs of autism except that he is a bit delayed with speech. He only has 1 word but has a lot of signs and is very communicative otherwise.
Anyway, just wondering what could be up and what you'd do, seems overkill to get in touch with a pro!
