Parents, when you put your kids to bed you hope they sleep through the night so you also might be able to sleep through the night. Sometimes they get hungry, thirsty, or sometimes they need a diaper changed or maybe they just had a bad dream. Some kids sleep through the night, others are up every so many hours. As the kids get older, they start having friends over for "Sleepovers". As they get older, these "sleepovers" turn in to staying up till 4 am playing video games and then sleeping until noon or so. I tripped over this video on YouTube of twin two-year-old boys, who's parents were wondering why the boys were tired during the day, so they set up a video and this is what they discovered. You get the entire night in just two minutes. You will notice the parents coming into the room a few times too.

Enjoy.
