I told an Occupational Therapist that DS1 (ASD) crawled at 7 months and she seemed surprised (in a nice way) and it reminded me of an awful SN nurse who visited us at home pre dx who took some basic details from us about his development. She asked the 'Did he crawl?' question then started to tick no before I replied . In the accounts I have read, the jury seems out on whether crawling or the age of crawling really is significant or not. Is there a common belief that ASD children are less likely to crawl and is it based (partly) on reality?
