One of my new favorite theologian moms alerted me to the new one-sized pocket diapers, Bum Genius 3.0. They look like an improvement over the old Fuzzi Bunz and Happy Heinys. Although I should also point out that Happy Heinys also recently came out with a one-sized diaper. I've never seen the latter in person, so don't take this is an all-out endorsement.
The other baby gear addition I wanted to mention is stick sunblock. It is so much easier than lotion, and we couldn't survive the summer without it.
