My boss is 7 months pregnant. Yesterday, in a sudden burst of energy, she cleaned and rearranged her office. She attributed this to “nesting”, saying that pregnant women get urges to do things like this. I had never heard of such a thing.
I have very limited experience with pregnant women (single, no kids, thank god), but this makes sense to me. Perhaps it is an instinctual holdover from the time when we made nests out of tall grass and leaves and such, like the mountain gorillas.
Is there any scientific evidence of an increased nesting instinct in pregnant women? If no science, any anecdotal evidence for or against such a thing?
