As a gynaecologist reminded a friend of mine the day she confirmed her pregnancy: \”Your breasts are for your husband, not your baby.\”
Breasts do not exist so as to feed the baby. The milk glands do, sure, but the actual breasts are there for men to go \”Wooo Titties! Boobies!\” over.
Other mammals have the milk glands but only humans have the titties you see…..
