I am also fairly new and getting ready for an arrival this April
. I am a 1st time mum and as such have no experience either. I know that in the back of some of the baby mags there are ads from Little lambs and they will send you a free nappy to try, you can choose size and material. I don't know how well they work but they are super cute!
Good luck and keep me posted on how you get on, would love to hear from other cloth newbies on how they get on too xx
