As the child gets older the more frequent night feeding is not a normal condition and may be related to insufficient feeding, lack of vitamin D or calcium, and bad habits. 1. Inadequate feeding: As the child gets older, the need for feeding increases. If the need for feeding is not met in time, the child may get hungry more frequently, hence the frequent need for night feeding. 2. Lack of vitamin D or calcium: some children may cry at night if they lack vitamin D or calcium, and parents will feed their children habitually after they cry, so they may mistakenly think that their children’s demand for nighttime milk has increased. 3. Bad habits: Some children may sleep with the nipple in their mouths and become more dependent on the nipple. It should be noted that generally speaking, with the normal developmental pattern of the child, the number of night feeding should be gradually reduced. Therefore, once the above situation occurs, it is recommended to actively search for the cause and deal with it accordingly.
