Can anyone recommend good sites for covers? I have some AIO's and some pockets but for the most part I want to do prefolds and covers. I have a local store where I plan to buy diaper service quality pre-folds used at a great price. Piper was a really tiny baby, 5lbs 9oz and remianed pretty tiny. She was always in the 25% for weight and went up and down in height but was always below the 50%. Hoping some of you have experience with ones that are better for little babies. TIA!!
