Wet nursing was a huge way to exploit motherhood in slavery. Wet nurses could only be women who had babies of their own, so slave owners would use those women to nurse their babies. Instead of paying a woman to wet nurse, they would just enforce wet nursing on their slaves, commodifying these women's motherhood to nurse babies that aren't theirs. They would separate black mothers from their children, therefore creating and perpetuating this stereotype of black mothers either leaving or not caring for their own children. This would obviously take a huge psychological toll on the enslaved women, being forced to care and feed children that are not their own without choice. Their children go hungry, with the only possibility of seeing them is if they are allowed into the yard and happen to pass by their child. They also used breastfeeding as a form of birth control for enslaved women, because breastfeeding can act as a natural birth control. At least for the first six months after childbirth, your body can stop ovulating, therefore not being able to get pregnant. Another way to keep black women under control of their masters in every way possible, down to their fertility.
