What about supplementing with my own milk?
If mothers need to supplement their baby, it is nearly always best to use their own breast milk or colostrum. To do this, mothers need to express by pumping, by using their hands (manual expression), or by a combination of the two. A hand pump may be good for occasional expression, but a double electric pump, which pumps both breasts at the same time, is generally considered better at maintaining milk production if mothers are pumping regularly. They are also generally more effective than single pumps and produce more milk in less time. Milk can be expressed after the baby has breastfed or instead of breastfeeding and stored for the next feed or frozen for later use. Colostrum can be expressed by pregnant women and stored frozen for use after the birth of the baby.
