We're at the end of reception and eldest gets on well with everyone in the class, but doesn't seem to have strong friendship with anyone in particular. There's a few kids mentioned that they like to play with but I've noticed at recent parties that they tend to hang out as a little group that DC isn't part of.
What point in school did your DC find their "people"? Their school is a big city school and I do worry sometimes it's too big... Missing that sense of close community as there's simply too many people to get to know.
