I'm agonising over this.
Mid August 2012 born DC and we've had confirmation from the council that yes, DC can start reception in 2017 rather than 2016. We've got to make the final decision by mid January when school applications have to be in.
I feel like if I knew what other parents of summer borns are planning it would make my decision easier (all the children in DC's 'year' group at preschool seem to be Sept-Dec 2011/Jan/Feb 2012 birthdays so it doesn't apply to them, I don't know anyone else with a summer 2012 child!).
DC is developing normally as far as we know, no SN, just a lot smaller and very 'young' compared to peers at preschool. I just want to make the best decision for DC both for now and in the long run.
If you have a summer born 2012 DC what are you planning on doing?
