Many pregnant women find that toward the end of their third trimester, they experience something called the 'nesting instinct' or nesting phase - basically, it's the urge to prepare for your baby's arrival by rearranging furniture, feeling the need to wash baby clothes, and wanting to do some general spring cleaning! Nesting urges are completely natural for moms to be, and aren't just unique to human pregnancy - all kinds of pregnant animals have a nesting instinct in some form! However, for people, this burst of energy tends to manifest in more human behavior like cleaning and organizing. It's worth noting that not all pregnant women experience an intense nesting urge, and that's absolutely fine too - whether you're scrubbing the bathtub or putting your feet up before your due date, you've got this!
