Starlling: I swear by my sprayer! I can't imagine not having one. My sister who has cloth diapered 8 kiddos doesn't seem to think its a neccesary item but DH and I disagree! We also have a bucket that DH rigged up similar to the potty pail system and I love it!
The pattern I use for knitting longies is the picky pants pattern from Little Turtle Knits. I've been really happy with the few pairs I've done. I want to knit a few soakers too. I'll also be doing a couple of cocoons and just putting the baby in a t-shirt and diaper and using the cocoon as a cover. They look so snuggly! The nice thing about knitting newborn sizes is that the project goes fast!
