Since we're totally sure we want an only child, I've thought about how it might not be worthwhile for us to get tons of baby gear. I don't want to deal with getting rid of all that stuff, and there aren't a lot of families with babies in our area or babies in our own families!
If you knew you weren't having a second child to save things for, what would you not get? For instance, I've always wanted to cloth diaper, but am not sure I can justify it.
