One thing all of those who care for little ones will know is how much children love staying up past their bedtime - but you might be shocked to find out what time they should actually go to sleep.

According to experts, the answer to that question all depends on their age and what time they woke up that day. As we previously reported , a sleep chart circulated by a teacher at Wilson Elementary School in America on Facebook says five year olds should be going to bed as early as 6.45pm, depending what time they woke up that day.

For children aged eight and nine, bedtime should be any time between 7.30pm and 8.45pm-9pm.

Covering ages five to 12, the chart shows that children aged five should go to bed from 6.45pm to 8.15pm, depending on their wake-up time.

Meanwhile, kids aged 11 and 12 should be asleep anytime from 8.15pm to 9.45pm.

However, it adds that if your five year old gets up at 6.30am, they'll be ready to go to sleep at 7.15pm.

But if they woke up slightly later than 7am, they'll be ready to nod off at 7.
