I know this topic has been discussed before, but for some reason I have not been able to find the previous posts on the matter. I am considering giving my 5 year old and my 3 year old a dose before bedtime, because they are SOOOO hyperactive at bedtime and have a very difficult time settling in. They also sometimes have trouble sleeping at night, and my OLDER child, she is 12 is really our difficult child, and her psychiatrist suggested it for her, but being much older, I figured it would be fine to give her. But at three and five, I know there are certain dosages that parents have used at these ages and had wonderful results, but I was worried because I don't want to overdose them..... I have 3mg tablets on hand, that my 12 year old takes two of at night, is ONE 3mg tablet too much for my younger ones? If so, should I get a lower dose, or can the 3mg be broken in half? I am also curious to hear everyone's experience with this medication and when the best time to give it. Is it 15 or 20 minutes before bed, or RIGHT AT bedtime?
