DS (2.11) has been moved from the tweenies room to the preschoolers room at his nursery, where he goes twice a week. First few times he has absolutely loved it, however this morning he got really upset and said he didn't want to go. Took him into the Tweenies room instead and the staff suggested they would take him up to preschool later.
They took him up there at 2pm, and he played happily but got upset later in the afternoon.
I picked him up at 5pm, and another little boy saw me and started pushing him towards me. I think the little boy was just trying to be helpful but DS burst into tears 
Anyway took him home and he has been sat on the sofa with me and he has told me "me don't like preschool". I asked him why and he said "boy hit me, a little boy and a big boy hit me and hurt me. Me scared of them"
Going to talk to the nursery about this, I am wondering if the staff are aware of this, if they would only speak to the other boys' mums and not me, or should I expect them to tell me something like this?
I have told DS he can go to tweenies for now but he will need to go to Preschool in the new year as he will be three then.
Just going to put DS to bed then I'll check for replies.
TIA.
