What is the best bottle to use for a preemie?

Premie nipples: Each baby is unique. Smaller preterm babies may need to use a "premie" nipple for the first few months. The bottle itself is a matter of preference, yours and the baby's! remember, babies, especially preterm, have very small stomachs. Don't overfeed.

Trial and error: You need to figure this out through trial and error. Search online and read the blogs. Then bring your baby and see which bottles and nipples are closest fitting to your baby. You will need to try a few until you find one that works.
