Ethan smiles all the time--unless he is sleepy or hungry. Even then he usually just whimpers a bit. Rocky (our little fluffy white dog) provides endless entertainment for Ethan, and he even reached out to pet Rocky this week! When Rocky barks, Ethan giggles. When Rocky tries to jump between us (the dog can be a bit jealous!), Ethan thinks it is hilarious. Last week Rocky barked incessantly when I came home without Ethan--he was so confused and concerned about his little friend!
