My son was put on meds last week (he's 4 years old). I didn't start him on them till today, cause he goes to preschool 4 days a week, and I wanted to wait till Christmas break, so I could see for myself how he would react to them. The past few hours he has told me that he has a 'bad feeling' about things. I try to get him to elaborate on this, but he just says he feels bad. Any ideas? Should I stop giving him the meds? This is the 2nd time he has taken them. The first was Friday before last, and I didn't like how he acted then, so I decided to wait till his break.
