Sleep plays a very important role in both the physical and mental development of children. Letting children sleep alone is a way to improve sleep, thereby helping children develop most comprehensively.

Getting your child to sleep with his or her siblings can be difficult. Therefore, mothers should have appropriate solutions to minimize the impact on the quality of family life.

According to experts, parents should train their children to sleep alone completely when they are 3 years old. However, the decision of when to let your child sleep alone depends on the child's health and psychology, as well as the situation and your feelings when having to sleep alone with your child.
