I know how ridiculous some of these things are. Sometimes I feel like smacking people in the forehead and making the Homer Simpson "doh!" sound.
At the same time, I found myself understanding the beauty of things I never thought I'd rely on before I actually had a baby: say, the swing (when DD had reflux and barely ever slept and needed to be upright a lot and we were all going out of our minds) or Disney/Sesame Street/etc. videos (during this second pregnancy when I felt awful and was desperate for
anything that would make my toddler stay still for a while so I could stay still for a while). (In fact, DD is watching video clips on Sesamestreet.org on the other half of the screen as I type this!) Actually having a kid will knock most self-righteousness right out of a mom-to-be--at least it did for me!

I am a huge proponent of registries and I always buy from them. There may be a reason why the "practical" things aren't on someone's registry (she already has them from a previous shower or borrowed things from friends, etc.). Also, I'd rather have a friend get me a wacky earth mom thing from my registry (say, two dozen cotton washcloths for my homebirth) even if she thought it was ridiculous than decide "for my own good" that I needed, say, an exersaucer. I mean, maybe she
loved her exersaucer, but I don't want one, thanks. I try to extend the same courtesy to my friends that I hope they'll extend to me.
