Bum-mer.

I think you're on the right track. You are not engaging her, encouraging her--good. I have had experiences when I was not interested in talking to someone. When I can avoid answering (phone/txt/email) I do. Their reaction is their choice. When they're knocking on the door, I have been known to interrupt their opening gambit with my own "Sorry, I'm not interested, thanks." and shut the door. There's just that one sentence and then the conversation's over.

It doesn't seem like this is enough to make her stop, given that she's still after you and Bean for five months now. I would consider escalating the example I gave with something like "Sorry, my baby's asleep, good night." Why else would you want to have a longer conversation with her? Maybe she has some novel, unknown information for you? Your lights are on in your car. Your house is on fire. A previously unknown cache of Twinkies has been discovered (no dairy, no chocolate). Whatever. If it IS important, she'll press. Until she does, just close the conversation.

The next level of go away might use these words: "You're really bothering me--leave me alone!". Perhaps it could escalate into calling the cops. Or having a restraining order filed. I have done/had done unto me all the above. Something will work. Eventually, she'll give up. If she's not utterly clueless, one of these BIG BOLD ALLCAPS wave-offs will get it; mission accomplished. If she is completely clueless, she needs big loud messages to make it clear.
