When introducing formula to a breastfed baby at night, do so slowly and with caution. A baby that is used to breast milk may not like the taste of formula or may have digestive issues when it is first introduced. This is especially true of children with milk allergies. 

Be on the lookout for signs of discomfort and stop use if your baby becomes constipated or gassy. Speak with your pediatrician about other options for formula if the one you are using doesn’t seem to be the right fit.

Is It OK to Give One Bottle of Formula at Night?

Yes. You can give as many bottles of formula at night as you need to, as long as you know your baby is satiated.

Never starve your child at night when you know that he or she is truly hungry. Babies can learn to sleep through the night as early as 6 months, however, many parents find their children to require nighttime feedings even into toddlerhood.
