I am starting to love my one BumGenius 3.0....the fit is finally working out for my 2 month old chubber and in a nice way! I recently picked up 2 seconds of the 4.0 at the CottonBabies sale. I am hoping the snaps make me LOOOVE the BumGenius as much as I want to love them! I picked up an elemental recently and I would love to add more to my stash, but I'm cheap! Maybe I can convince myself to pick up some more in the future.
Spreading the love for BumGenius! I will be posting what I think on my new 4.0's once I get to try them out!
