I can tell when she has something with food coloring....ultimately we have rages. She just had one....she's being overly emotional, difficult and oppositional. I sent her to her room......rages. I had her appoligize to the girl who's watching them while I work and told the girl this is what happens. This is the first time she has seen Missy like this. I told her that I suspected that it was because Missy had something she wasn't supposed to. I asked Missy and fortunately, she didn't lie. She fessed up to having a blue lollipop. Corn syrup and food coloring. Corn syrup makes her over-emotional and hyper. The food coloring makes her rage. She has been doing sneaky things lately. It's bugging me. She keeps getting caught, so I hope that she realizes soon, that when she's sneaky, she gets into trouble. I didn't punish her for the lollipop, since she told me the truth. She was sent to her room for the behavior....I think that was punishement enough (I hope). On a side note....as punishments, I've been making her write things like "I will not be sneaky" or I will not hurt my brother. Her handwriting has gotten much better.
