Whatever and however you help your child to enjoy reading and then writing PLEASE as a heartfelt request from a primary school teacher DON'T teach them to write their name all in CAPITAL LETTERS!
It's a far harder job to unlearn things than to learn them in the first place and the number of minor battles I've had with children over "My mummy/daddy/gran said that was how to do it" would make me rich if I was paid for each one. Same thing goes for letter formation - try and find out the school's way of doing it and do it the same way.
I know from experience I've had to check the school's writing policy on going into a new one on supply. It's amazing what you find out!
