Re: I will be a new momma
agree with other posters to try out several kinds. get what you can used off of here- some great diapers for good prices which is great if you dont know what you'll like.
personally i stocked up on bumgenius organics when pregnant with #1 (and a few bumgenius 4.0 pockets) and then when he was born i wanted to try other kinds, even though iwas happy with those. turns out the organics are still my favorite.
i never got into prefolds/covers but did get a few fitteds and covers when he started leaking through pockets/all-in-ones at night.
it can be overwhelming. but give them a try. if you want to see the diapers- youtube has a cloth diaper channel that does reviews on them and its nice to see the diapers and features.
