So up until a month ago our little boy who has an asc diagnosis and global developmental delay was able to go up the ladder at nursery to get onto the slide, nursery have told me over the last month he is no longer able to do this, he will lead his one to one to the slide but can no longer physically climb it, she has tried placing his feet on the steps but he can't seem to figure out how to do it. I'm really confused and worried about this. He has never been able to do actual stairs this is mure of a slanted ladder at nursery. Any ideas or advice would be amazing x
