"That's MINE!"

"You're not my friend anymore."

"I had it first."

"No one will play with me."

As parents of preschoolers, you've likely heard some of this language. As we think about formal schooling (preschool and Kindergarten) for our littles, we likely think first of the ABC's and 123's, the art activities that teach colors and shapes, name-writing practice--basic building blocks of an education. But one thing that may be easily overlooked at this age is the development of social skills.
