I think it is utterly crazy that you are forced to send a premature child to school at 4, even a none premature child at 4 if you think they are not ready for school. There was a thread on here recently about a child being made to go to school at 4 when he had developmental delays as well which was madness as another year at nursery would have benefitted him greatly.
I wonder where the law stands on this, if you refused to send you child to school until they were 5 would you be prosecuted? I suppose unlike the Scottish system if you defer you would lose your nursery place.
Christiana - I know it sounds mad but after realising that DD2 only gets 1 and 1/3 years at nursery when other children get 2 and will go to school at 4 1/2, we made the decision to hold off TTC#3 so they would at least have a March birthday but of course these things never go to plan and we lost our March baby and have a July one instead. The next one is due in May as well.
