I can 2nd this. As a parent of a level II autistic son and then 6 years later a now 1 year old girl that does not appear to have any autistic traits. We delayed having the 2nd child by years because the first was so draining. They are night and day. During parental leave I found it hard to play with my son in ways where he acknowledged that it was fun. He mostly did repetitive activities alone like flexing a folding rule or similar. My daughter is completely different. As parents our son Ahmad thought us a lot about not projecting our expectations onto the children and meeting them where they are.
