Sisterly Love, Right?

Not sure love was on our little girl's mind when she did this to her big brother. Kinda hard to see, but YES, those are teeth marks on his arm. Neither Ryan or I were in the room when it happened, but according to Dalton he did nothing to her. She simply grabbed his arm and chomped down. I'm hoping this was just a rare occurrence, but what fun if it's only beginning. We did not have to go through this with Dalton so hopefully the stern talk and time out will suffice and we no longer have an issue. We will pray.
