I know this is a way old thread, but I'd just add my thoughts. Since you have so many in dipes and DH seems to be resistant to the idea of CDing, be sure to make it as simple as possible. This is where I went wrong - buying too many different brands, styles, etc., and made it all too confusing and time-consuming. Also made it seem so much easier to just use 'sposies.
So, I'd recommend something one-size, either prefolds, fitteds, or AIOs (Wonderoos, BumGenius!, etc.). Or maybe some Kissaluvs 0s for the NB until he/she moves up to fitting better into the one-size.
Keep it simple, and you'll keep your sanity.
Plus, you'll stay on the CDing wagon!
