Pros: Easy to wash
Cons: Overnight protection is lacking
We have a full stash of BG 4.0s and we love them. We have been using them since 9 weeks old, before then they were leaky for us. I don't believe that the leaking had anything to do with the diaper rather, the fit on our baby which is different for everyone. We 'sized up' rather quickly. At 22lbs and 29 inches the diaper is at full extention.
We also send these to daycare with our baby without any isses. They are easy to wash and dry.
We do get overnight leaks with these. I have heard great things about stuffing the pocket with bamboo to up the absorbancy but for use, a disposable works best overnight. There are even nights when our little one leaks through the disposable.
All in all I think this is a great diaper and a good choice for a cloth diapering family who works outside the home.
