DS is 3.8yrs and attends nursery every morning. He is the youngest in his class. Most of the others are 4.5ish.
On Monday walking home a few of the kids had run on ahead and when we got to where we turn into our street I said "come on DS" to him, only to have another boy say "yes go away" and push DS over. This boys Mum didn't see it and I just ignored it and carried on home with DS (with him crying the rest of the way home that X had pushed him).
Then today coming home the kids run ahead as usual, one of the girls fell off a scooter so DS goes over to her and says "are you ok", to which this same boy runs over and shouts "shut up stupid" at him. Again I never said anything, just walked off with DS. The boys Mum didn't see it again.
I'm annoyed at myself for not saying anything, but really, what is appropriate for me to say?? I don't feel it's my place to say anything to this boy, but he is so horrible to DS for no reason! Is this just one of those things that I need to get used to or should I mention it to the boys Mum or nursery teacher? I really don't want to come across as being precious (even though I'm well aware I probably am!)
