Sick For The Holidays!

Well, I have been living on let's see now.... 6 hours in 3 days of sleep. Sam is teething and has decided instead of sleeping he wants to stay up and play and cry. When I say play I mean making Spiderman webbing sounds. So now I am getting sick I think. Or just so over tired my body is shutting down. But even with just a little sleep himself Sam still looks like this every morning, a big smile. How does that work?
