Will she take a bottle?
I use the bottle teat with the ring and put it into bubba's mouth and then squirt the medicine into the teat as he sucks away at it, voila! Much the same as the dummy I guess but he wouldn't take that either.
We now use this method for pamol and other thicker meds too, use a cross cut teat for the thicker ones.
Hope it helps
