There are many changes in our postpartum bodies that can change our body odor, both the amount and smell. First, we are getting rid of excess body fluid in the postpartum phase. Thus, we sweat more than normal. Yay. There is also a change in our hormones. This may be so that our newborns can recognize us while their eyesight is adjusting to the outside world. This also may be the reason our most potent body odor comes from our armpits. This odor leads a newborn directly to the food source!
