Not much to add to the title, really - just wondering how old your DC was when (s)he started playing with others. The kid will happily play alongside others, and says she likes them and calls them friends, but pre-school say she doesn't play with them, and seem to think this is an issue. She's only 3.7 though, so I'd have thought that to be perfectly normal?
Just after your experiences. She's an only one, and didn't go to any child-care before pre-school, and so until she started she didn't see large groups of other children.
Thanks in advance.
