Shot in the dark, have you considered her diet?

I know that adelaide reacts like she's on speed to a large amount of the 200 range of preservatives. Especially the propionites (found in bread, 282 mostly), and the sulfites (used as preservative in so much stuff).

Another side effect Adelaide shows apart from the manicness is also impulse control issues, which yeah, doesn't help in the very young.
