My son is four , in reception and young for his age . He can be quite sensitive and shy . When he initially started in reception another older boy in his class kept pushing him , squeezing his face etc etc . I had a word with the teacher should I thought fairly defensive . It stopped until this week . Now he has come home with a mark in his groin after bring punched there and last night a mark on his back from the same child . I am quite a shy person too and don't like yo make a fuss but I mentioned it up his teacher who said she was sure it was just a one off and boys playing together . Now he has returned with another mark ..... What would you do ? I really like the teacher involved and don't want to be a trouble maker but cannot let this continue .
