The difference between
the maximum and minimum breast volumes is attributed
solely to the milk in the breast. That is, when the breast is
at its maximum volume for the day, the storage capacity of
the breast dictates the amount of milk available to the baby.
Breastfeeding storage capacities in mothers who are exclusively
breastfeeding range from 81 to 606 mL.40 The
breastfeeding storage capacity is not necessarily unchangeable
for each mother.
