For children aged 1-2 years, what is the optimal sleep time per day?

For children aged 1-2 years, the optimal sleep time per day is considered to be 11-14 hours. This range accommodates the significant growth and developmental changes that occur during this stage. Adequate sleep is essential for cognitive development, emotional regulation, and general health in toddlers.

At this age, sleep patterns typically include a longer period of nighttime sleep, often supplemented by one or two daytime naps. During this developmental phase, children may require varying amounts of sleep depending on their individual needs, but staying within the 11-14 hour range supports their physical and mental well-being.

Choosing a different range, such as 9-11 hours, would not provide sufficient rest necessary for a child of this age, while the upper limits of 12-15 hours, although beneficial in some cases, may be more than what is typically needed for this age group, potentially affecting their daytime alertness and activity levels.
