Hi
After much deliberation (and chats with Mumsnet mums!) we've decided to delay entry to P1 for our DS2 until 2006 (he is Jan birthday, so could start in either Aug05 or 06). Thanks to all who answered my requests for advice about how being eldest/youngest in class affects boys at Secondary School.
We are happy with our decision (Nursery teacher calmed our fears that we may harm him somehow by delaying, she only had positive things to say about boys being eldest in class instead of very youngest, at both Primary and Secondary levels).
