My DT2 has had this since he was 8 months (now 2.5) and it has a big effect on his sleep - he's chronically sleep deprived as a result of rocking on his hands and knees when he wakes at night.
I read online that NT children usually grow out of it by age 3 but there's no mention of this happening with children who have asd. Or at least I can't find any evidence.
Does anyone have experience of it stopping? Or is my poor boys sleep ruined forever?
