"I'm Tired"

When Collin gets tired, besides around his eyes getting red, he wipes eyes or his nose with the back his hand a few times or he takes the front of his fingers and wipes both hands down his face starting with his eyes. He does this a few times and then can barely walk, he is so tired. But....does he want to go to bed or take a nap....not way. He continues to wipe and play but it not interested in going to his room. We know that within 20 minutes of him doing this, he is out!
