There's a child in DS nursery class who has a real problem with being physical with several of the (usually quieter and smaller) kids. DS is a tiny 3yo and that's boy is a big 4yo.
For us it's daily reports of being kicked and pinched, but he's also given two of DS friends black eyes and one burst lip.
This has been going on for months on a daily basis and the only feedback any of us get from the nursery is "we're aware and there's a strategy in place".
It's now taking a mental toll on DS, coming home quiet and clingy and saying he doesn't want to tell the teachers because it makes problem child angry.
I feel for the boy because he's clearly got something going on, but realistically it can't be allowed to continually affect an entire cohort of children.
