Once we got home - Grandma gave Megan one of the special cookies she had made just for her. Megan loved it, of course. Then Megan wanted to make sure everyone knew how the kitty cat's ate their food (flashbacks to her new friends Bebe, Buddy and Bear).... either that, or she just liked looking at herself in the metal tray. (your guess is as good as mine)
Sidenote - this was the same highchair that Tom used when he was a little tyke.
