Why is milk produced only after delivery, not before?

#Biochemistry

Levels of luteinizing hormone and follicle-stimulating hormone are too low during pregnancy to support milk production
High levels of progesterone and estrogen during pregnancy suppress milk production
The alveolar cells of the breast do not reach maturity until after delivery
High levels of oxytocin are required for milk production to begin, and oxytocin is not secreted until the baby stimulates the nipple
