We recently found out we are expecting again and since I've started using cloth on my 8 month old and already decided I really like the bum genius one size diapers, I was thinking of just getting more of those and use them for both babies. First, how many do you think I will need (my eight month old only has 3 one size diapers- the rest are other pockets and prefolds) and also, how do the bum genius one size diapers really work on the tiny ones? My first daughter was 8 lbs 4 oz, so I am not expecting a really teensy baby this time either..but will they be too bulky? any experience? Thank You!!
