Before anyone says 'stealth boast' this is NOT I am genuinely heartbroken watching my son on the side of every soft play, every group.
My son will be two in three weeks and has incredibly good speech and comprehension. He speaks in short sentences, describes things, knows loads of shapes (including ones like hexagon), counts, etc. Now don't get me wrong, I am blown away by this and love hearing him talk and having proper conversations with him.
Unfortunately it seems to have become a massive divider with other children. I've had him at playgroups consistently since six weeks old, to be fair even before speech he wasn't exactly friendly with other kids but it's got far worse. A few times he tried to talk to other kids and when they didn't understand/ couldn't answer he began completely avoiding them.
He seems genuinely frightened of other children and will not play unless I'll follow. I don't want to 'helicopter mum' but he will stand stubbornly next to me until I go with.
I know at his age he's not exactly going to be playing collaboratively but he runs from other children, hides and will flat out not even go near a part of a soft play with more than two children.
Older children, like my younger brother and sister (12 and 11) he will play hide and seek, draw with them, play with trains, dance with them and chat to them but when with his peers he finds a corner and hides :(
