Spoke today with teacher at day care who was unhappy with what was said as she states that she has none of those concerns with him. Yes he at times goes to la la land but can be brought back and re engaged, she states that he is involved in group time and they do fairly complex topics at times have done in last 18 months while he has been in kinder room space, astronauts, geology and rocks etc, science experiments etc. She stated in last 6 months she has seen massive growth in him.

So that eased my worry a fair bit.
