How do you deal with shopping when you don't know the sex? I'm asking because when we were waiting, we bought a lot of gender neutral stuff, but in the end when we got our babies we almost never used them... I know it shouldn't matter, but when you have a girl, you don't really want to dress her in gender neutral greens and yellows, lol. We never even bothered with the nursery until later though, so it wasn't a problem (and plain white sheets worked just fine for the cribs).
I guess you could just buy a few onesies, go neutral for car seats, and go shopping when the baby is born...
