When my dd was 3 and in pre-k her teacher mentioned to me that dd would play fine one on one with another child but that as soon as another child would join (or more) dd would leave the group.

Dd is 7 now in 2nd grade and apparently she still does this (spoke with the recess monitor). She will only play one on one with children and if anybody else comes along she leaves the group.

She also separates herself on the carpet in class during instruction and will always sit far apart from the group.

I asked dd about the one on one play and she said more than one kid at a time makes her uncomfortable. I tried to ask more to try and understand how it makes her uncomfortable and she got frustrated and said she didn't want to talk about it.

Is this a red flag? Asperger's has been something I have been concerned about.
