The Olivia Rollercoaster

As I was preparing dinner, Olivia can roaring through the kitchen with the daddy and boy from her dollhouse hanging out the front of her shirt. I'm not sure why, but I asked her what she was doing. She said, "being the Olivia rollercoaster."

So, what does a 20-month-old boy with hummus running down his face have to do upon seeing his big sister running around being a rollercoaster? Run after her with a big smile copying everything she does, of course!
