I used almost exclusively Sunbaby diapers on my daughter till she started potty training. (I had a few Kawaii Good Night Heavy Wetters but only like 6 of them.)
I loved it. The first thing to remember is microfiber inserts suck. They're prone to compression leaks, and that means you get pee on your leg if you sit the baby on it long enough. Nope nope nope. I switched to bamboo inserts pretty quickly! Bamboo absorbs a LOT more, and is much thinner too. (And doesn't compression leak everywhere.)
I did laundry every 2-3 days, so not bad. I was using pocket diapers, so they do require stuffing. That takes about 15-20 min, and I usually was watching TV or Netflix while doing it. Wasn't bad at all. The savings were incredible. I paid $160 for my stash of Sunbabys. (
www.sunbabydiapers.com) I got 2.25 years worth of diapering out of them. When my daughter started potty training, I sold them on for $80. So, overall, I spent about $80 in diapers for 2.25 years.
Granted, there's still laundry costs to consider, but when most people will tell you they spend $80-100 every two months on diapers... there's no chance you're spending more than that on laundry!
Not only that? But they're ADORABLE. Disposables are... not cute. Not at all. I don't care that Huggies puts Mickey on their diapers, they're still ugly. Cloth diapers come in so many prints and you can get so many different styles, and they're ADORABLE. Nothing like seeing a cute little fluffy butt!
Someone else mentions wishing they'd gone for the one size from the start. That depends on how big your kids tend to be. My daughter was itty bitty (5lb 15oz) and it took 3 months or so for one size to fit her, so I've already ordered newborn size for this baby. If you have big babies with chunky thighs, you might be able to go straight to one size though.
Good luck! I'm very pro-cloth. I loved it. I was almost sad that my daughter potty trained cause no more cute bums! LOL
Edit to add: Oh, and bonus! A lot of cloth diapered kids *do* potty train earlier. (Not all, but some.) That could be helpful with two in cloth.
