Well I am not much help since I got my boy at 9 months but I am sure your girl will outgrow this phase. As for the jumping you will get great advice here but in the meantime when she jumps turn around and give your back to her. She will learn that she isnt getting your attention like she wants. As for the rough play, my boys used to play so rough I thought Cutty was going to bite off Mugsy's little "chicken leg" but they ended up ok. It was scary to watch but they were having fun and managed just fine.
