My son is almost 5. We started it on the weekend to see if he had any side effects. First thing I noticed was he seemed worsed. More hyper and then fusey he even had a twitch with his mouth. When he talk to me it was as if there was a delay. His mouth would move and he look like he was really trying to tell me and then the words would come out. I know this is his first day but I'm feeling so nervous. I felt so bad for him today. I'm not sure if this is the right one or not for him. Almost scared to try for day 2. Has anyone experience this with there child?
