Children can slowly wean themselves off nighttime milk at six months after birth for two main reasons: First, children are ready to wean themselves off nighttime milk. At six months of age, children have already added complementary foods and can stop drinking milk for about six hours after one nighttime drink before bedtime without feeling significantly hungry. Secondly, not weaning at night can affect the sleep of children and parents. If a child eats milk frequently at night, it will not only affect the parents’ sleep and cause a decrease in milk production, but also affect the sleep habits of the child, so that sleep quality is not guaranteed. As we can see above, it is better for children to be weaned from night milk six months after birth.
