My son is only just four so the youngest in his class but for the last three weeks happily ran into class happy as larry. Then suddenly this morning after our normal routine we got to the school gate and he started stamping feet refusing to go into class then telling me his knee hurt then pretend crying (I could see he was smiling!!) has anyone else experienced this...i know it's terrible but I really felt myself getting angry especially with all the other mums staring and laughing and his baby sister crying. Any advice would be greatfully received.
