How the tool works

To get these results, we’ve used the information you entered to work out the average sleep cycle pattern for each child. We’ve also factored in the amount of time it takes for children to fall asleep after bedtime, which may be substantially longer on Christmas Eve.

The results we’ve given you are when we estimate that your child(ren) will be at the deepest point of their sleep cycle. This means they are the best times for you to start setting out Christmas presents, as you’ll have less chance of waking them up.
