"Let's get a sister."

Grant, bless his heart, loves to play with Rhett. The problem is that Rhett is, well, a baby, and doesn't exactly play the way Grant plays with his peers. Grant tries to play nicely, and he tries to play fairly (most of the time). I often hear comments like, "We can play with it together, Rhett." This statement, although sweet, is impossible because Rhett does not know how to share, and thus the sibling fights begin. Tonight is no exception. Rhett accidentally dropped a toy on Grant's head which really hurt Grant's feelings. He just does not comprehend that Rhett truly was innocent in the ordeal. Grant told Rhett he needed to say he was sorry, but after getting no response from Rhett (big surprise), Grant marched over to me and said, "I don't want a brother. Let's get a sister!" and placed himself in his room to play alone. Would he admit that he truly loves his little bro and enjoys playing with him (most of the time)???
