Today my DS (5) told me one of his classmates came up to him while he was playing hide and seek with another child and punched him hard enough to make him fall over and hurt his leg. He said this child, who he’d thought was a friend for a few days at the start of term, has been hitting other children for a while now and they ply with different groups of kids. When he got hurt my DS told the classroom assistant who put a cold compress on his leg and told him to tell his teacher. He did and both he and the other kid were asked to clarify what happened - then my son was sent away and the other kid was punished. I heard nothing from the school so this is all on the word of a 5-year old.
My son’s been having trouble sleeping and being unsettled emotionally lately, and I wonder if this kid picking on him / being violent to others might have something to do with it. At any rate he asked to sleep in his little brother’s room tonight and as he was going to sleep asked if maybe the other kid didn’t get enough sleep and maybe that made him hit other people.
My questions are: should I be speaking to the school / teacher at all to understand what’s been happening better, or just leave them to it unless my son’s sleep problems get worse? What is the best thing to tell my son about how to act at school and about why the other kid is acting like this?
