ds(11) has had a cough for over a week, today developed a rash . gp has prescribed meds but also I gave piriton at about 3.30. Now we can't remember whether I gave him one spoon or two , nor can he, and when I went to give him a bedtime dose realised it should have been 1 Obviously we gave him no more. Max dose is 6 spoons in 24 hours so assume he'll be ok , if sleepy ?
