Sorry you are having this problem with your little one. I have some of the same issues with hyperactivity, but I just tire him out playing with him and then he goes and sits down to rest. Let him run around the yard and play with her. After that, he is mellow for the rest of the day.
When company comes over, he is really happy to see them and wants their attention, now here is the good part, my guest are happy to see him as well and they pick him up, get some kisses, rub him and talk to him, then all is well. He is happy because he got his acknowledgment.
They love love love attention, so if she is not getting enough from you, she may very well do something bad just to get some attention from you. Dont let the tiny size fool you, they are super intelligent and want their way. You just have to find ways to make them believe they are getting their way when it's really your way.
Hope this was helpful.
