My son is 9.5 months old and 8.8kg. his birth weight was 3.325kg. do we need to keep up with night feeds? if not, how do we stop them and hopefully get him to sleep through the night?

No/change: At that size you can certainly stop night feeds. There are 2 important issues to avoid night feeds. First, never feed them closer than 1/2 hr prior to bedtime. If they incorporate into the sleep ritual they require it to go back to sleep on night waking. Second, begin reducing night feed quantity & then switch to water. They will adjust over a week or so & stop waking to feed.

Growth/development: If your son is otherwise healthy and developing normally, the night feedings may be stopped. He should have three meals and two snacks in addition to his formula daily. A variety of fruits, vegetables, rice cereal/grains and lean protein are important components of his diet and help to reduce night hunger. Review his growth chart with his pediatrician.
