Younger babies sleep a long time, most of the day in sleep, if the body and appetite development are relatively good, generally do not need special parental intervention; on the contrary, if the baby sleeps for too long in the afternoon, especially more than 4 hours or more, accompanied by sleep chirping, decreased appetite or the biological clock reversal and so on, it is recommended that parents need to wake up the baby.
