Silly question I know but for a long time I gave dd 5ml spoon of periton per4-6hrs. It said 5ml spoon on doctors lable so I just always gave it. Now I worry as I have done so for as long as I can remember. Recently dawned on me that that measurement was incase she had a anaphylactic reaction, the reason why I had been given it to begin with but I have regulary given it for her itchy eczema aswell. What do you give? I am right to only give 2.5ml for her normally and not 5ml. I spoke to my dermatologist and she acted like only 2.5ml but it then doesnt seem to do anything. Just thought I'd double check to see what you all give. I know it says 2.5ml on the bottle
