What do I do?!

It's 6:00 where I live. We were watching a movie with my 15 month old, and when I looked down I noticed he fell asleep. He had one 45 nap today during the drive home.. the holidays have been hectic so this is our first day home since christmas morning. He's never fallen asleep in my lap before and he's currently in his crib (another place he's never slept before) ahah. My question is- seeing as it's so early, should I wake him up? Or let him sleep?
