Randall Neustaedter (an oriental medicine doc) recs 1/4 tsp cod liver oil per 12 lbs. of body weight for "infants." For children 3 yrs and older, 1 tsp clo per 50 lbs of body weight. This is from his Child Health Guide book (2005). We use the clo so DH and I can take it too. We don't give every day, especially now that it's summer. Just FYI, Mercola's website recently went on a tirade about not giving cod liver oil b/c of vitamin A it contains. I haven't done more research on the topic, but just continue to use a variety of fatty acids. Hope this helps!
