Nathan: on a personal note my son is really growing. He's almost 5 months now and at his last weight check he is 17 pounds and 27 inches long. He's got a tooth or two wanting to come up from the bottom gum and they should emerge any day now. It's a neat milestone for him. He's sleeping in his swing as I type this and he just lifted his head and started laughing without ever waking up. Crazy guy!
