I have a daughter born 29th May. She is currently 3, due to start school next year.
I am currently thinking about deferring her, but only if she is able to start in reception the following year.
Would most people think that is crazy? She is not developmentally behind as such, although she is not fully toilet trained yet. I have been trying for months, but she still has more than one accident a day.
My reasoning is more based on how I feel about the education system in general. I don't mind reception as it's still very play based, but I hate the idea of 5 year olds going into key stage 1 and starting formal education so young. I have 3 older sons, none of them summer born, so have never been able to make this decision.
