She will not attempt to wrestle with him as she used to and even now when we go outside to play, she will hide behind us instead of playing in the yard. She has never done this before and it is so sad to see. We don’t know how to help her. Our boy and her have always played rough, and since she has become so timid, we have begun behavior modifications for him to see if this will make a difference. Which is confusing to him, as his behavior was always accepted by our girl as perfectly fine and fun! We are just at a loss. Please help!
