I'd take the opportunity to learn from it. She won't get hurt. Wesley jumps on my 16 month old and can knock her onto her bottom and he also tries to steal her food from her. She only gets a little startled, but is never hurt.
I'd love to hear some input on how to kick this behavior.
Only thing I've really read or heard is that when they approach people they are to sit. If they sit there, you give them a reward.
Not sure about what to do about the food stealing though...
& two human rugrats!
