Fully 95% of the time, A's a cuddly, kissy sweetheart. But if you disturb her equilibrium in any way, by say, postponing a meal, placing her food directly on her highchair tray instead of on a plate, brushing her teeth with baby toothpaste instead of the grape stuff her big sister gets or trying to wrangle her into clothes, pajamas or a clean diaper, she will unleash the beast within.
She's also been known to lash out at inanimate objects. Throwing food I understand. Babies do that. Drop-kicking sippy cups of overly watered-down juice? It's kind of amusing. But biting your dolly's bed because the rug has stopped its progress across the hardwood floor? And then bursting into tears because biting the hard wood bed frame didn't feel so great? That takes the cake, kiddo.
