This is my favorite newborn diaper out of all the brands we've used so far. My second daughter was born small (6lbs and dropped to 5lbs 2oz) and these fit her perfectly. No leg gaps, no leaks. I love the semi-removable insert which makes line-drying really quick. We only bought two to try. Definitely buying more of these!
I used these for about a month, month and a half, until my youngest was big enough for the best bottoms (my oldest was in OS pockets, and I wanted to avoid the leakage that happened with a teeny baby and huge diaper butt). They are a good bridge until you get a bigger diaper. I'll reuse them again for the next baby.
