Pros: great fit, no leaks
Cons: on the expensive side
I love my bum genius 4.0's! They are a trim fit and we have never had a leak. We use have used them for the past two months on my 4.5 mo old. She is super long and thin so some diapers just don't work well for us (like the fuzzibunz). I just wish they offered more pattern choices. I thought I would get tired of stuffing pockets but they are so much quicker to dry than all in ones. I like the BG inserts and have not yet had to double up whereas I have with sunbaby.
