*I've only been CDing for a little over a month and didn't start until my baby was 4 months old and 16 pounds, so take my advice for what it's worth!*
Has anyone tried/liked/disliked these? Other recommendations?
I've used thirsties and thirsties duos - I like them both - nothing has escaped them yet :) I've also used Bummis whisper wraps and bummis super brights - they fit a little better overthe fitted diapers I have but the legs don't seem as leak proof. It's nice to have a little variety.
What are the best prefolds to use?
If you are going to mainly use prefolds, I highly recommend Green Mountain Diapers (aka Cloth-eez) prefolds. The quality is great, and they have five sizes, I think, versus the standard two (infant and premium). We currently use red edge (medium) prefolds, and I don't have to do any folding to fit them in medium covers. If you are just going to have prefolds as a backup to fitteds or another method, then you should be able to get a good quality prefold from most cloth diaper sites.
Is it better to use prefitted diapers under a diaper cover (like the Thirsty brands)?
Fitteds hold in runny baby poop better and make for quicker diaper changes than prefolds. On the other hand, they cost more and some are not as absorbent. In my experience the Thirsties fitteds fit great but aren't super absorbent.
Are one size covers better than S-M-L?
I've never tried any one size covers, but I do have a couple Thirsties duos (comes in two sizes to cover from birth to potty training), and I really like them. Thirsties claims that most one size covers don't fit newborns or bigger toddlers; something to keep in mind, but I don't know how true it is. I'd rather have the sized covers just because I feel like they fit a little better than one size, and I plan on CDing my next child and hopefully some of the covers will still be useable with baby #2.
Any info anyone has to offer is greatly appreciated. Thank you so much!!!
You can't go wrong buying some prefolds - even if you never use them to diaper, they make great burp cloths and changing pads :)
