Ahh. The nesting phase of pregnancy. If you haven't hit it quite yet, odds are good that sometime late in your third trimester, you'll suddenly find yourself incessantly cleaning, organizing, and/or disinfecting every square inch of your house to prepare for your little one's arrival. And believe it or not, the whole nesting thing isn't all in your head.
According to a new study published in the journal Evolution & Human Behavior, nesting is a primal instinct in pregnant women that stems from a desire to provide a safe environment for their unborn baby.
And while I can't really recall entering the nesting phase myself when I had my son, many moms admit going to extremes to make sure everything was in tip-top shape before they went into labor.
