Hindmilk makes up the last two-thirds of the milk in each breast. It
contains more fat than the rest of the milk, called foremilk, so it is rich in
calories and nutrients. It is important for babies to breastfeed long enough
on one breast to get the hindmilk.
To get to the hindmilk, breastfeeding (or pumping) should continue
on one breast until it is emptied. This usually requires at least 10 to 20
minutes of breastfeeding per breast.
