My son who is 5 (July born) is in year 1 at school. He does love school although they have a horrid behavioural system of putting their name on the cloud for a warning about something and then the storm cloud which means they miss golden time (essentially special play time) if they continue with their behaviour. I am aware he did have his name on the cloud a lot before half term because his teacher said he calls out the answers etc during carpet time and this meant my son would come out saying he didnt want to talk about his day as it upsets him quite a lot. Anyway, he seems to like his teacher, has a great group of friends and is very clever. He had been complaining about a tummy ache before half term and then towards the end of half term he started again, this morning he had one but I checked him over and he was fine. He was happy in the car and happy walking into the school grounds with his friends. As soon as he reached the door he changed and broke down in tears screaming he didnt want to go in and repeating 'I'm tired' it was such an instant change in his behaviour I was really shocked and could feel myself getting upset aswell. I asked him if he was worried or had something happened that maybe I had missed?! He said no and just kept repeating 'I'm tired' after 10 mins or so he reluctantly came to the door albeit still crying and luckily one of his friends saw him and put their arm around him. He still went in crying. I phoned school half hour later and they said he is fine now. I am just worried I am missing something? He hasn't had any major changes and he had a lovely half term with a mixture of activities and relaxing. I spoke to his teacher at the door ( who is very wet anyway) who just said that he to is also tired! and cant think of any reason he might be upset. He had also had a great day at school yesterday so I was just really shocked. Any suggestions/reassurances anyone can offer? Just sat feeling a little teary now and concerned (maybe worrying too much like I do!)
