Austin insists that McKenna eat with him every meal. When she happens to be napping, he gets upset that she's not sitting is "Aus seat!" I actually thought he would be more possessive about his booster seat, but I think that lasted only for a moment. He does however, get possessive if I put her in the big high chair. McKenna, for her part, loves sitting in her chair. From there, she can watch her big brother eat and laugh at his antics. She just thinks he is the funniest kid!
