A newborn baby with black and white sleep reversal can cause less stable sleep for the parents, which can lead to less adequate sleep and less breast milk production. This situation in children needs to be corrected in a timely manner and can be dealt with in the following ways. First of all, we should create a good environment for the child, for example, parents must be quiet at night, and the light at night should not be too bright, so as to create a dark environment for the child. Parents should not speak too loudly, but relatively softly, so that the child gradually feel the difference between the day and night environment, in order to ensure that the child sleep quietly. When the child sleeps at night, the child must be fed, only eat enough milk powder to sleep quietly, otherwise they will often wake up in the middle of the night, and thus can not obviously have a complete night sleep.
