What does Addie like to drink?

What does Addie like to drink?
It may be hard to deduce from looking at these pictures.

Any guesses?

Here's a hint--despite what this picture may seem to evidence, her favorite drinks are non-alcoholic.

In addition to the normal staples of milk, water and juice, in the last week Addie has imbibed:

• caffeine free Dr. Pepper. We'll be in trouble once she discovers the hard stuff
• lip gloss, though not for the first time. She also attempted to change the color of her eyes with said lip gloss.
• most of a bottle of gripe water (homeopathic colic treatment). Was she feeling gassy?
• the remainders of a bottle of teething tablets, mostly powder by that point. She is cutting her 2 year molars, so . . . .
• a tube of baby toothpaste
• 3 times (3 times!) she has snuck into the diaper bag and emptied the contents of the formula container into her mouth. I could understand trying it once, but going back? You'd think the smell would have slowed her down. Maggie won't even touch the stuff. I guess it's good someone's drinking it.
• and finally, guess what was in the bottle she's just polished off?

One final hint--it wasn't formula.
