Two-year-old children have difficulty falling asleep for more reasons, mainly as follows: 1, parents do not create a quiet and comfortable sleep environment for children, such as putting TV in the bedroom, too many toys in the bedroom, etc.; 2, did not develop good sleep habits, holding sleep or must drink milk to fall asleep; 3, full of energy, there is nowhere to vent; 4, too excited before bed, such as watching TV, playing. There are also cases where parents go to work during the day and return home late at night, and children are too excited to see their parents; 5. Irregularity in life and rest. When young children have difficulty falling asleep, first of all, we should develop a good routine, regular bedtime and wake-up time, remove bad sleep habits, and put them to bed after the appearance of sleep signals have not yet fallen asleep, so that they can fall asleep independently. Second, establish sleep rituals. Establishing sleep rituals before the age of one helps to build parent-child relationships and can help children to form sleep conditioned reflexes, and fixed sleep rituals can also help to establish circadian sleep patterns. A sleep ritual is a quiet schedule for children to have a fixed and orderly sequence of 3-4 bedtime activities to spend a pleasant time together, such as brushing teeth, bathing, changing clothes, going to the toilet, parent-child reading, and going to bed to say good night.
