I was so happy to find these when my son was born. He was born 7 weeks early and I still wanted to cloth diaper, despite his small size.
I bought these (the preemie size is such a great deal on Amazon!) in 'preemie' and used them with the newborn Bummis Super Brite covers and they worked PERFECTLY together. My son started wearing them when he was 6 pounds and he wore them for about 8 weeks until he was 9 pounds.
I really liked that I didn't have to try and get my little guy into a cover with an infant sized prefold. I had some of those and they just were enormous. He could use them as a blanket!!
I also really appreciate that they are organic. That was important to me and I'm so glad I found these.
