I want to play with the big kids!

My parents live in a great neighborhood with about 20 kids all around the same age. For the most part, they all play really well together and are great when other kids come over to play. Sofia is by far the youngest of this group of kids and they are all really good with her, especially the girls. As soon as Sofia hears them laughing outside, she runs to my parent's front door and can't wait for one of us to take her outside. She mostly just watches them all play, but has the time of her life.
