LEARN your teenager's SLEEP pattern!!

Sometimes, getting your teenager up in the morning can be like trying to wake the dead. And when you do manage to haul them out, they act like a zombie. Often, they've been up to the wee small hours of the night before, but trying to convince them to go to bed earlier can be a losing battle.

Your teenager's sleeping patterns may drive you mad, but there is a likely reason for those bleary eyes.
