Hmm... well, I wouldn't personally choose gdiapers. Maybe you'd like grovias I think there is another hybrid out besides those two as well but can't think of it.
Personally though, I think you could totally handle usual cloth diapers even with two. I had 2 kids in diapers with the last birth and will have 2 kids in diapers again (most likely) with this one too. It's not biggy. You just need to wash cloth diapers probably every day. And it saves you lots of money.
Diapers I've liked...
I like the dream-eze aios and fitteds but they don't make them anymore. I think some of the grovia stuff is like the old dream-eze stuff so you could look at those.(Grovia OS AIO looks like a dream-eze but OS instead of sized.) The nice thing with the dream-eze fitteds and AIOs is they had a sewn on one size insert that was split in two layers so it is very quick drying.
I like contour diapers a lot. I have some imse vimse ones but they aren't as absorbent as I'd like. Once baby gets to be like 5 or 6 months they need a nice thick doubler with the imse vimse OS contours. The imse vimse flannelette OS contours fold down very well for a newborn, but the terry ones are a bit bulky.
I like double gusset covers. My favorite for now are the Thirsties sized covers. I have also done alright with the bummis super brites.
trifold hemp inserts - used as doublers - LOVE! Would totally work as a newborn diaper as well. I got mine on clearance for $2 a piece. Big score!
I'm OK with the old thirsties AIO/pockets. They make Thirsties duo diapers instead now. They may be worth a try though I haven't tried those specifically.
Sandy's fitted diapers - they work fine, but I like other ones better.
I've done prefolds with covers successfully but I'm a bit lazy and like other types of diapers better for that reason. Also prefolds seem to always bunch up for me, it doesn't effect performance but it is a bit annoying. If I couldn't afford anything else. I'd get double gusset covers and prefolds. I liked using a snappi with my prefolds. It's a good idea to get some doublers or larger sized prefolds
that you can fold down for extra absorbency for night time and naps - especially when your baby is older.
I like the large PUL wet bags in a 13 gal kitchen garbage can for my diaper bin. I also use a 5 gallon bucket for putting diapers I've sprayed off with a the very handy diaper sprayer.
I really like the small zip wet bags for going out of the house.
Diapers I've hated:
Kushies AIOs - first diapers recommended to me and they sucked. Never kept in a single blowout.
Knickernappies - I don't like the gussets and I had some leaking issues
Smartipants - horrible fit!
Fuzzibunz OS - they work alright but the biggest problem I ran into was pee wicking onto clothes with those and I almost never had that problem with other systems.
Proraps AIO - it's OK, but it's size is off. Order a size larger if you are close to the next size and the velcro isn't very good.
MEOS (mother-ease one size) - way to thick in the middle. Will leave your kid waddling around and may be too bulky for a small baby.
booroi covers - they work alright, but I wouldn't trust them with blowouts. - best on older kids - and the covers bleed for a little while, so you have to prep them.
kissaluvs cheaper doublers - might as well not even bother
Small drawstring wet bags - they work but not as well as the zipper kind.
My favorite diaper review site:
A mistake I'll try to save you all from - Do not invest a ton of money into one system until you are sure you will love it. I learned multiple times the hard way.
With the one exception being if you are seriously poor - in that case, go with good old prefolds, snappis (if you want) and for me double gusset covers but for others it'd be fleece or wool cuz they don't like PUL.
That's all I remember for now. I hope that is helpful to some of you. :)
