LO (2 yo) has been at his new nursery for a few weeks now and settled in well. His group is 20 2-6 year olds supervised by two nursery nurses. He was at a creche before with 10 kids aged 0-3 supervised by two nursery nurses. He is a very friendly boy and seems quite popular among his playmates, especially the older girls, but one 6 yo boy is worrying me a bit. Unlike any of the other boys his age, he's always trying to touch LO and the other younger ones and chase after them when they don't want him to. It seems like LO isn't that interested in his company as when the older boy tried to give him a leaf he'd picked up when I was dropping him off LO just said "no" and ran away. We try to teach LO that he should say if he doesn't like someone touching him and that his personal space is important, but this boy seems to invade that quite a lot and I dread to think what it's like when I'm not there. Has anyone else had any experience of this? What did you do?
