I think I know what you're talking about. It's for pediasure, I think. Is it the one where the mother is like, "did you know ___is good for you? Did you know that___helps you grow? Well, what DO you know?!" Girl, the first thing I noticed on that commercial was that little girl's lips. Maybe, it was the residue or backwash from the drink...
