I probably ate 3 or 4 a feed, cos I'm greedy. Fed every two hours. Actually, I'm amazed I never gained weight during that time! This was when DD was probably 5 months old. It was also the height of my supply. Feeding we every two hours at least, as well as pumping about a litre a day (2 sessions). Never thought that maybe the cookies might have contributed? But to answer your question, I ate 3-4 and was generous with the active ingredients.
