I kept my son at home as he had a disturbed night and woke clearly tired and not functioning well.My son came home today and informed me that his teacher has told him that he has to come to school when he is tired. I feel uncomfortable now as I as his mum judged him to be unable to cope with the school day. Has anyone here had related difficulties in managing the demands of primary school on their four year old children, and any advice for how to help young four year olds to manage in the same way as their older classmates?
