Thank you mamas... it's good to know we're not the only ones going thru this.
For us, I don't really see a pattern to it, like she wants me to stop doing something, or she wants my full attantion, or anything like that. Many times it has absolutely nothing to do with me... I catch her doing it to get a reaction out of her twin sister. So, as much as I ignore it, she's still got an audience there. And it seems like the more I try to distract her and move to something else, the more agressively she does it... again, to further entertain her sis.
I can usually ignore it until she stops, but the self-induced vomitting really got to me.
I hope that was an isolated incident, because I'm really at a loss as to how to react to that one. We were riding in the car when it happened, and when we got home I was going to start cooking her another meal, but dh thought maybe if she had to go to bed hungry as a result of her own actions, it might be a good lesson for her. I'm not sure...
Looking forward to this stage being a distant memory, for sure!
