My first roller coaster

Tonight we went to Lucy's new house. It has a roller coaster inside! Mama decided we should ride the roller coaster to the second floor. Their diaper changing pad was upstairs and mama said the roller coaster was nice for people holding squirmy babies. I don't know about squirmy babies, but I thought it was good fun. Mama says roller coasters get even bigger and faster when I'm older. I can't wait!
