For the sake of achieving the goal, you can go the other way and come up with a fairy tale for the baby about the good doctor, whose name is the tablet, and who seeks to cure all sick kids. But, telling the story about the doctor, be sure to focus on the fact that the doctor cannot cope with children’s ailments alone and asks for help from your son or daughter. Most likely, the child will sincerely express the desire to help a fabulous hero. And then you will need to say that for this he only needs to take an unpleasant medicine to taste, that, most likely, the child will hasten to do.
