What's more annoying than a self-absorbed pregnant woman?

Nothing.

I just saw a report on "belly buds," adhesive earphones pregnant women stick onto their bellies for babies to hear music clearly while in the womb. I'm not sure why, but this really annoyed me. If there's anything I can't stand, it's pregnant women who act like they're the only person in the world who has ever been pregnant, and they do all these self-indulgent things that won't really help their child's development. They act as if all the things they are doing for their pregnancy are going to help their child be better looking or something. Belly buds, prenatal yoga, cloth diapers. GET OVER IT.
You want your kid to be smart? Spend time with your kid once it's outside of your body, and don't dump them off with someone else. You want your child to have tenacity and a strong sense of development, read them a book, or actually talk to them. Playing Mozart to a fetus won't make your kid a genius, or you any more of a pretentious hipster than you already are.
