Do give the prefolds a try, though--they're easier than you think! I have been impressed with how much I've LOVED them so far, this time around; we used them for my son six years ago, but with a laundering service. This time I'm doing it all myself, and gosh, what was I afraid of? Easy peasy. And getting prefolds on and off: a snap(pi). Har har. But seriously, I undressed and redressed her for a weight check at the pediatrician's office yesterday, and the nurse was like "...Wait, that's it? But that's so simple!" Yes!
And yes, totally just use the pockets as covers. I like my PUL covers because they are so incredibly easy to keep clean, but if you already have the pockets, by all means!
She's here! Baby Yoshiko arrived on 2/7/15, and now we are a family of five.
