who is having more fun?

I pulled out the exersaucer that Thomas loved at Meredith's age so she could give it a whirl. She is enjoying the new things to look at, esp. the fun looks on Thomas' face as he spins this thing around and around. He loves that it pivots so he can push it and that the toys are all interchangeable. She just likes to be vertical and looking at her brother. It's a toss up as to which one is having the better time!
