first time cloth nappy user

this is my second pregnancy. I made the decision to use cloth nappies about a week ago. my reasons are all the usual: they are the cutest things, save a bunch of much needed money and as a bonus good for the environment! Then I also have other reasons like my first child has very sensitive skin. she gets rashes super quick and can't use any product on her skin. with her I didn't consider cloth diapers as I was a newbie mom. I regret that now. when she was 5 months old, we were on vacation looking for a swimming nappy and so I stumbled upon the cloth nappy. I couldn't resist buying one and I LOVE it. so this time round I am proud to say that I will be using cloth nappies. I figured out most but i would like to know how many I should buy (excluding newborn) if I wash every day. I'm going to wash every day as I function better in a daily routine. thanks in advance
