just venting

Little one got bit twice by the same toddler at daycare today. The biter belongs to my coworker of all people. I know he was just frustrated and cannot communicate yet (he wanted the ball she was playing with). I'm not upset with him, his mom or the sitter at all... I know these things happen but it breaks my heart to see little girl's arm all bruised. It's going to be close to 80 this weekend and I feel like I need to keep her arms covered so it doesn't look like we abuse the poor kid.
