Spoonful of Sugar?

The 2.5-year-old is on the verge of out-lawyering me.  Didn't want to take her medicine.  Two nights in a row I pulled the 'big girl' card ("Can you drink your medicine like a big girl?") and it worked.  Tried it again last night.  She said no, pitched a fit, and just for good measure said, "When you are a little girl, you can drink the medicine."
