Diapers are a weird thing. I think you have to try them, nearly all of them, to really decide what works for your baby and what doesn't. I can't speak to cloth diapers (I wanted to go this route but it just didn't work out that way), and we tried the hybrid gDiapers with limited success. But disposables are one of those things that are all over the map. Even if you find a brand you like, it could be wildly different once your baby moves to a different size.
For example, we were Pampers fans for the newborn sizes. They just seemed softer to me, and dang that stripe that changes colors when they pee is GENIUS! But, once we got to size 2 and 3, we were Huggies fans all the way. The size 2 and 3 Pampers just didn't fit my guy properly - they were stiff, and loose between the legs. The Huggies hourglass shape suited him much better at that size. And now, onto size 4, we're back to rockin' the Pampers. Can't stand the Huggies in this size. Weird, huh? I also really like the Kirkland diapers from Costco, which rumor has it are just Huggies anyway, so go figure!
It's all a matter of preference really - Pampers are thinner, and less bulky, while Huggies are cushy and thick. For my guy's shape (thin, no belly, no butt!), the less bulk in the Pampers fits him much better.
My guy has a tendency to pee a LOT overnight, even though we've stopped his bedtime bottle. The Huggies Overnights were useless on him, he leaked almost every time. I blame the fit, more than the diaper capactiy (He has NO belly, so Huggies are floppy on him and the pee would leak right out the loose top). Pampers Extra Protection do a fine job, with the occasional leak (usually the diaper can't handle the volume).
Recently, I bought a pack of Happy Nights by Fisher Price. I believe these are sold exclusively at Babies and Toys 'R Us stores, at least for now. (they are also online at Amazon)
So far, we've been leak-free and I really like them! They are on the square side, and look so thin I didn't believe they would work, but we've been leak free all week, and they aren't over saturated in the morning. The tabs fit smoothly, nice and tight, which is important in an overnight diaper, especially for a boy!
They are also cheaper than the Pampers or Huggies (Happy Nights: (size 4) 38 cents per diaper, with the $2 coupon below, I paid 27 cents per, vs 40 cents per diaper being the cheapest I've seen the Pampers)
You can find out more info here, as well as print a $2.00 coupon. (thanks for the high value coupons, Fisher Price!)
Based on the good experience so far, I'd be willing to try out the Happy Days as well. They also sell a combo pack with 64 Happy Days & 18 Happy Nights Diapers per package (size 4).
