DS2 is a March baby so can start school at either 4 turning 5 or 5 turning 6. His older siblings where at a school where FYOS was 5 turning 6 and that's what we did. We are at a new school now and have the option to start at 4 and Iam not sure what to do. I am not keen on the earlier starting. I was up to 18 m younger then my peers all through school and as we got older this was definitely not a good thing amd ai ended up repeating yr 11 but itvwas the social side of things that caused the most problems. (Big difference in a 14 yr old and almost 16 year old. ) I do believe a later start date is best and most research seems to support that but I am worried he will be bored towards the end. I look at my older two and DD is thriving and DS1 is struggling so can't look at them for comparison. It would have been terrible if DS1 started at 4, DD would have beer fine. I am very confused!
