One of the coolest things I get to do as a mom is watch the sweet relationship bud between two brothers. Calvin just loves Charlie. He loves to watch Charlie's every move. Charlie likes to make Calvin smile and laugh. He likes to give Calvin kisses and hugs. He brings Calvin stuffed animals and baby toys. We are working very hard on the concepts of being gentle and giving the baby some personal space (i.e. not sitting on the baby). Calvin is such a good sport about Charlie being a little to rough at times still, and only cries if he is actually hurt.
