Aidan's most recent words have been "excuse me" after burping, "you're welcome" (he used to say thank you, too after hearing thank you) and then with his usual humor, "no hug daddy" or "no hug mommy" which means that he wants to get a hug. His vocabulary is really very extensive, so the list is long. It includes whole sentences like, "Mommy, come here, sit next to Aidan", and "I want to go work with Daddy", and then it includes short sentences and negatives like "no go night-night".
We went to visit our travel mate (the grandmother, not the mother and child) at the fire station where she works, he got all excited about having ham for lunch, he checked out every tool in my brother's furniture making shop, he went to his aunt and uncle's 25th wedding anniversary party, visited my brother's garage where one of the caterpillars was inside being worked on (he calls every yellow earth mover a caterpillar), and has generally been very busy.
