I used to think this was very cute/nice, but now I'm starting to feel a bit concerned although I don't really know why. Ds (nearly 4) loves other children, to the extent that he likes to touch them a lot - eg. puts his arm around them, pats them on the back/shoulder, rubs his hand through their hair, and sometimes puts his face very close to theirs when he's talking to them. His preschool teachers have noticed his affection toward other kids but haven't made a big deal of it, they just simply tell him (as best they can) to be mindful of other people's 'personal space', because not all children like to be touched.
From watching him interact with other kids, some kids don't like it and they tend to back away, while other kids don't seem to mind. He seems to strike up 'playground' friendships quite easily and will often pair up with another child as if they're best friends, but there are definitely children around that don't appear to like this 'over familiarity' or closeness from a child they don't know. I hate seeing the looks they give him sometimes and the way they pull away from him (mostly older children), and occasionally I've noticed that other mothers seem to feel threatened by it, as though he's getting too close to their child. Should he be more aware of personal space at his age? I am just wondering whether this is a normal thing for children to do, or whether it can be an indication of something else because to be honest, I don't see many kids doing it.
Any input would be appreciated... thanks.
