How to stop night feeding

Hello some babies learn to sleep through the night only after 18 months or so. it differs from baby to baby. my baby is 15 months old and she still wakes up twice in the night sometimes even thrice. However we limited the feed to only twice, one formula feed about 120ml when she wakes up in the middle of the night, later early in the morning she will wake up once during which I breastfeed. One thing you can do to prolong the interval of the night wakeups is by giving a good solid food (preferably rice) in the last feed about 2 hrs before her sleep time. Just before sleep you can give 150-180ml formula. This helped to make her sleep atleast 4 hours at a stretch. Hope it helps
