It's a common assumption that nursing a child is a cause of drooping breasts. The truth is that it is the strain of pregnancy, not breastfeeding, that often creates the appearance of sagging.
Whether a mother plans to breastfeed the child or not, breasts naturally enlarge as the body prepares for nine months of gestation leading up to the moment of childbirth.
When the breasts begin to return to their normal size, the degree of skin laxity will determine whether the skin will also return to its pre-pregnancy tone and integrity.
If your skin lacks sufficient flexibility, the breasts will appear to droop, sometimes resulting in a so-called “pancake” look.
This chain of events will not be influenced by the decisions you make as to whether to breastfeed your infant, and for how long.
