My DD was 8 lb 13 oz at birth, and I used newborn prefolds with her for about 3-4 months. She did gain weight very slowly, though, due to a milk intolerance that I didn't figure out very quickly. I loved the prowraps covers for before the cord fell off, and then I think I used Thirsties. The prowraps were also great for her skinny legs, which may not be an issue for you.
