G.F.
It would help to know what type of meds you are trying to get her to take. I have three year old twins and I've found getting either cold/cough meds or prescriptions meds with the right flavoring helps. Mine hate anything orange flavored, but will do grape flavored. If it's a prescription med, most of your pharmacies will mix a flavor in for you upon request. I have also found that my kids now do meds better taking it from an actual teaspoon vs using the medicine droppers. I think it makes them feel in more control of the situation. I always tell them when we have to do medcines they need their medicine to make them feel better. For some of the really aweful tasting meds (a few of the antibodics even with flavoring are just terrible tasting), I've actually mixed in with a little bit of their favorite go-gurt yogurt flavor.
Wish you luck.
