Nesting — it's not just for mama birds. The urge to clean, organize, and otherwise prepare your home for the arrival of a baby is common among human mothers, too. It's not a medical condition, but that doesn't mean it's not a real biological instinct. That being said, not every expectant mom will be a "nester." But for those who feel the urge to gather twigs (or, in our case, crib sheets), you may find that it's a rather satisfying experience. In my opinion, nesting is the best part of pregnancy.
To be clear, there's very little that I find enjoyable about being pregnant. I am grateful to my body for its ability to carry this little life inside me, but honestly, I feel miserable most of the time. Between hyperemesis gravidarum (HG) in the first trimester to hemorrhoid surgery in the second to severe backache in the third, well, I'll take any positive aspect I can get. For me, that's nesting. I have a type A personality, and I love the process of putting my house in order, so to speak. I derive significant pleasure from washing and folding little clothes and organizing them into boxes by size.
