When the boys were finished seeing each animal, they would wave good-bye. In fact, waving has become an important part of our routine - especially for Calvin. He waves at EVERYTHING (his blanket, room, toys, cup, etc.), the best part is that it signals the end of things for him which helps with obedience. Patrick has been working on obedience and is doing a great job at following 2-3 step instructions. He laughs all the time and has become extremely cuddly and affectionate which we all love!
