I had twin babies visit our home and Noodles (10) was very interested. I tried to make sure she got enough attention, but she clearly felt that she was deprived, as she flew right in the middle of the action (despite being a terrible flyer who only takes flight when terrified or RIDICULOUSLY motivated). That having been said, she never went after the babies or anything like that...I think she was actually shocked that she flew where she had intended, and it was more of a matter of her knowing that everyone was equally appreciated...herself included....ugh lol--Now if they lived with me, there could be jealously, but as a rule, she has done very well with crazy kids and babies...so long as they don't push into her space (at the same time, I am super aware that she could feel threatened so I attend to her frequently in order to make sure she isn't feeling insecure).
