This morning while we were getting ready in the bathroom Munchkin was walking around the edge of the bathtub. We have a big garden tub with a rock wall around it so it was pretty safe. When she would get to the outside area where it was much narrower she would call her brother over and say please hold my hand. He would walk with her along that edge until they got to the wide area again. That just melted my heart. I pray they are best friends and love each other like that for all time!
