Just turned 3 year old DS goes 2 full days to nursery and has recently moved up to the next room. He has always had nothing but positive reports on his behaviour at nursery and outside of nursery he is also very sociable and great/very kind with other children. There is a few specific friends he speaks very fondly of but last week (only his second week in the room) as soon as we left and I was strapping him into the car he told me 'John was kicking me in the back today and my back feels sore'. I got him back out of the car to enquire about this as they hadn't mentioned anything at pick up. It was brushed off and the lady told me she hadn't seen this but said the room is very not heavy and some of the boys (not DS) can play very rough and that was that basically. Today I picked him up and when I asked what he had been up to today he told me and then said this same boy had been snatching the toys off him, I asked if he was told off by the staff but apparently he wasn't. I know which boy he is referring to and from what I've seen and heard at the few pick ups his behaviour isn't great in general. I get some kids might snatch but alongside the kicking incident which was just brushed right off I feel worried about him being there all day around this certain boy if nothings being done.
I'm not sure if I should bring it up again and mention the kicking/new incident from today? He's not back until next Tuesday but it'll be playing on my mind until then. Am I just being naive and is this just the kind of thing I should be expecting from nursery? We have never (to my knowledge that he or the staff have told me about) had any incidents prior to him starting in this room. Luckily his communication is excellent so he can relay this kind of information to me otherwise I'd be none the wiser. He'll be in this room until he starts school in September 2026 so I want to feel confident in him being there.
