The sleeping time of young children varies in need at different ages, but is basically more than 10 hours. It is generally believed that the recommended daily sleep time for children aged 0 to 3 months is 14 to 17 hours; for children aged 4 to 11 months, they should sleep 12 to 15 hours a day; for children aged 1 to 2 years old, the recommended daily sleep time is about 11 to 14 hours; for children aged 3 to 5 years old, they need to sleep 10 to 13 hours throughout the day; and for children aged 6 to 13 years old, it is generally recommended that all-day sleep time should ideally reach 8~10 hours. To summarize, the sleep time of young children is different in different age groups. And it is worth mentioning that the growth and development of young children will not be affected only if they ensure sufficient sleep. Therefore, in order to ensure the healthy growth of children, we must ensure the quality of their sleep, and when the toddler sleep time is abnormal, we also need to consult the doctor in time.
