Ds is 4 in Jan 13 and due to start primary reception in sept 13. He can however choose to stay on at his nursery until after Easter 2014 if we so choose. Logically this seems like a good idea - he's a very lively little boy and would currently find sitting down and listening for extended periods hard. He his however quite bright, already beginning to read and write. Am I at risk of holding him back and leaving him behind his peers by deferring? Are there any other issues I should consider? Thanks.
