In general, it is best to wait to use a bottle until breastfeeding is well-established (typically in three to four weeks).
If your baby cannot latch-on or eat due to medical reasons, you can still express breastmilk and feed your baby from a dropper, spoon, cup or bottle. If you use a bottle, use a nipple that is slow flow.
Call your lactation resource before you start using a bottle.
