These covers prevent leaks, but I had to twist the wings for the leg holes to be small enough for my son's legs. The prints are cute too!
I love this cover! I grab for this one first and am sad if it gets poo on it and I have to wait until I do wash again.I do have to say that they do run a bit big.I started using them when my son hit 7 1/2 pounds it was still a little bulky but now that he is 9 pounds I am still on the smallest set of buttons with room to grow so I am thinking these will last for quite a while. We use these with flats and prefolds. Thank you for a great quality small priced diaper cover.
