SAHM, thank you for your support. We had a horrible day two days ago but things are perfectly calm again. I know I shouldn't complain since it'd be much harder if DD was difficult everyday instead of once in a blue moon but knowing that I am most likely the trigger makes me feel 100 times worse.
I had an interesting discussion with two friends over the latest episodes; one friend thought that DD is entitled to have one or two bad days a month and I need to just let them slide. The other friend thought it's all the sugar I feed her (frozen yogurt, smoothies, muffins, cupcakes, etc). I think they both are right. I don't believe sugar causes hyperactivity generally but I know I get really irritable when my sugar high starts coming down.
DD has been a master puppeteer since she was 10 months old. She was at a birthday party and she had two boys (3 & 4) competing for her attention and waiting on her hand and foot when they had so many fun activities to do instead. Everyone thought it was the cutest thing they've ever seen except I knew then I was heading into a real trouble.

If she was this skillful with non-verbal clues, how bad is it going to be when she starts talking? Raising a child who can read people's emotions as open books and knows exactly what to do and say to get what she wants out of people and situations is really, really scary.
