When he is not eating, he loves to watch what's going on around him. He has yet to smile on purpose, although he gives some sweet grins when he's sleeping. He is definitely showing his personality, and letting us know what he wants, when he wants it. By definition, this means "I want my binkie", "I want to eat", and "I want you to cuddle me to sleep".
He actually enjoys his daily baths, and seems to particularly like it when his head/hair gets scrubbed down. He has three medications he takes daily, and he is amazingly adept at swallowing it all down without gagging, choking, or fussing through it.
