3littlemonkeys - reading your post was exactly how I felt for DS1. We did hold him back. He is going really well at school and is one of the older ones in his class. He does get bored though and does play with the kids in the year above him a lot. I'm really finding it difficult with an April birthday. There is a little girl a few houses up from us and she is April too and is ready and going to school next year. Your point about the end of school is something to consider too. They will be a lot younger than their peers if they start next year.
