My 21 month old son woke up yesterday and after 8 months of regular walking he was toe walking all day and again today. I am really worried. I was already concerned he had a speech delay so this has driven my anxiety through the roof. I have no other concerns about his communication etc but i am just so confused as to why he just woke up yesterday and started walking differently. I know I will have to get this checked out but I’m looking for some reassurance.. did anyone have this when it didn’t turn out to be ASD?
