Baby led weaned babies tend to rely on milk for longer, which is good for baby because milk is still the most nutritious food they can have under the age of 1, and for mother because regular breastfeeding including night suckling contributes to reduced
oestrogen levels over a longer period, resulting in a lower risk of breast cancer later in life.
As women age, the pelvic floor muscles begin to weaken, either through childbirth, too much straining when eliminating the bowel
over the years, or, most commonly, due to reduced
oestrogen levels after menopause.
