I need some help with this: my 3 half year old had his nursery sports day today. It started at 3.30 and we had had a busy and exciting day in the city beforehand. We went to his sports day at 3.30 like all children who do not normally attend the nursery on a Friday. My son was tired and a bit keyed up but the event was an annual one and really special. He behaved really badly. He didn't listen to me and at one stage was tearing around charging into other children, I took him aside and he was slightly better but still continued to challenge me and generally attempt to cause a scene. He was quite aggressive and physical. He would have screamed blue murder had I just left and it would have spoilt the event for alot of people. I need some advice?
