Your milk storage capacity
Women generally produce the same amount of milk every day, but the quantity of milk that can be stored by each woman differs.
A woman’s milk storage capacity has nothing to do with the size of her breasts (breast size is a function of fatty tissue), but the size of her glandular tissue.
A woman with bigger tissue is able to store more milk and feed her child more milk at one feeding.
A woman with smaller glandular tissue can only give her baby small amounts of milk each time he feeds, meaning that the baby will require more frequent feeds to be filled.
