I find it very difficult to choose a nursery/primary school (if there is a choice!). My son can stay at his private nursery until he turns four (Nov '05). I am going to visit Colvestone, Gayhurst, London Fields, Princess May, Queensbridge and Shacklewell. Colvestone, Shacklewell and Princess May seem in our catchment area. Any advice which is best, when to start him at nursery to avoid too many switches, how big is your chance to get in to primary if your child is already in that nursery?
