This is today's pick....
This inner is for babies up to 10 lbs or so is an organic non bleached cotton. The name of them are Happy Heinies. It is super comfortable for baby and even has a snap to fold the diaper over the healing belly button. This one requires a cover and does NOT need a liner. I prefer snaps over Velcro for a snugger fit so when you wash them the Velcro does not stick to EVERYTHING!! I like the ones without covers for the first bit because you need to change them more often. Sometimes the All in Ones wear out faster the more you wash them, so this is my choice for the beginning.
This is my favorite cover made by a lady on ETSY.COM (my new favorite place to shop). Is is 100%wool, quite soft and not itchy, VERY breathable, and SUPER absorbent. It Also has a zillion snaps and will fit her from 5-25pounds!!
I also like the fact that I don't have to wash it all the time. If it gets a little wet I just air it out and wash it after a week or so of use. If poop gets on it I do wash it right away...obviously.
