For kids, taking tablets regularly can be a scary thing. You have to assure them that the medicine will help them. Explain to her that melatonin is something that the body naturally produces anyways, but she just needs a little more of it to help her sleep better at night. Create positivity and assurance between her and the medicine. You have to be honest with her, and not slip things into her food and drinks, or else she won't trust anything you give to her in the future, whether it be medicine, food, drinks, or anything else, and that would truly be a nightmare.
