I know on some level I am being PFB about this but he was 4 in Feb 2011, and just isn't interested in learning letters or putting them together. He loves us reading books to him, and with him, and he joins in, but isn't interested in learning to read. He's writing his name, under duress and would rather do colouring. So many other people that we know in his class for reception can already do some basic reading, so any tips / advice gratefully received...
