It takes one minute to get from your daughter\'s bedroom to your son\'s bedroom

Question

It takes one minute to get from your daughter's bedroom to your son's bedroom (they are on opposite sides of your mansion). You put your kids to be at 11 pm but each kid expects to be read a 20 minute bedtime story before midnight. Each kid's anger rises exponentially the longer they have to wait for you to show up, but they don't mind if you start the story and then repeatedly leave and come back (they just grow angrier and angrier the longer you are gone). This means you want to go back and forth as many times as possible, but with the constraint that you have to finish by midnight, having started at 11 p.m. How many minutes should you read during each stay with one of your kids? Please provide a process flows diagram.
