Linda, Thanks for sharing with us the article on whey:casein. I don't know who would test my milk, but I have a 4 yr old getting close to weaning (I think) and what little milk I have should certainly qualify as being close to the end of the lactation cycle. Would be interesting to see the results. Anyone in the N.O. area interested? Actually someone could probably go to a LLL meeting and find willing subjects to get milk from all stages of the lactation cycle; go to a toddler mtg and get the later moms.
