Dylan Thomas' poem Do not go gentle into that good night reminds me of my son very often when he is tired but forces himself to stay awake. We think that he knows when he is feeling tired and to keep from falling out sometimes he runs around screaming "watch out, watch out..." expending the last bit of energy he has left. Then as suddenly as he is whirling about, he might become exhausted and fall asleep nursing. It's really something to see. I hope he continues to approach life with the vigor and passion that characterizes these moments before he falls asleep. For now we're lucky to get to watch him rage against sleepy time.
