He misses Igor, his best buddy from the orphanage, and can't wait for him to come home with his new mom and dad (who happen to be friends of ours). When our schedule deviates, he needs constant reassurance of what the plan for the day is.
We're also starting to discuss the concepts of feelings, and how our actions affect the way other people feel. As in - if you break that, Alex will be angry. Do you want Alex to be angry? Clearly he's never put these emotions into words before. So good to be able to use words to build positive relationships.
