How much sleep should pre-kindergartners get?

As much as they want. My son needed lessee than my daughter

about 8 hours in the nighttime and 1 hour in the day

They still need lots of sleep to grow up better

They need more rest so the body can grow

More than 10 hours a bit too much

This includes their nap time too

At least 8 Hours of sleep.

8-10 hours is good enough

As much as possible?

8hours of kids a day
