Multiple personalities?

I wonder when Sybil’s parents figured out she had multiple personalities? I sometimes wonder if Mary does, for instance the little girl at the restaurant and the little girl who picked up her Daddy from the airport are two different kids! The highchair has become an issue, she sits at a little table at “Toddler Club” and someone must have told her only babies sit in the highchair because unless playdoh is involved she wants no part of it! She also is arching her back and screaming when I try to put her in the car seat, I called the expert (my sister Theresa) and she said sing Twinkle twinkle little star – it worked she was great! She also asks to wash her hands and sometimes her feet if she doesn’t think I am doing it often enough.  She also loves eating in the car and likes to take a “nack” with her.  This morning after she finished her “nack” she put all her pacis in the container and went to sleep holding on to it.
