You do not have to use either breastfeeding or bottle-feeding exclusively. For many mothers, a combination of breast and bottle is the best choice. You may choose to express breast milk and save it for bottle-feedings so another caretaker can feed your child when you're not available. Some mothers may also need to supplement their breast milk with formula if they're not producing enough. As long as your baby receives adequate nutrition, any combination of breastfeeding and bottle-feeding should suffice. Your pediatrician can provide more specific recommendations on the best way to feed your baby.
