Should i supplement lactation with formula?

It depends: This is a personal decision based on your baby's needs, your needs, & the amount of milk you're able to provide/pump. Your pediatrician can help you determine whether your baby is getting "enough" from breast milk alone. Timing of feedings may add another set of logistics too. Observe your baby & see what's needed. Review your own needs too. Formula can be a helpful addition in many cases.
