Now that's tired!

So, I don't "make" Austin take a nap on a daily basis, but sometimes he does fall asleep. Usually the routine is that he lays down in my bed for a little quiet time and then he ends up watching a movie. Yesterday I put on Transformers for him and I went back to check on him after about 40 minutes and this is what I found....
Now how tired do you have to be to fall asleep like this!? I couldn't resist crawling in there with him and snuggling for a little bit and he didn't even budge! He slept like this for about an hour. It must have been a very busy morning at school! Of course when it came to bedtime he wasn't tired and this is why we try to avoid actually sleeping at quiet time. He didn't look like he could help it this time though!
