Andre' , Some thoughts on Paleo infants and food. These are generated from my experience as a mother and my perceptions, as well as a look at early Christian human feces from the Sudan. First, my daughter was breast fed for 2 years. For the first ear she had almost no other food because she would not eat anything else. I did not buy canned baby food, but rather just ground up what we ate. We never did try porridge or cereals. Fruits were good and some vegetables were OK. Finely ground meat was also pretty good. As she ate more after her first year she ate more of the same types of things, never eating "traditional" baby foods. I would not be surprised if Paleo mothers fed their infants pre-chewed foods that they were eating. Therefore, the foods would vary with geography. I just can't imagine that any other special preparations were made. Mothers probably watched what their babies and young children liked and ate well and tried to give them more of what worked. My look at human feces from a population of early Christians living along the Nile River about 1400 years ago indicates that the infants and small children ate what the adults ate. This is not really ancient, but at least is not a modern population. As for age at weaning, look at physical anthropology studies. There is a lot of mortality at the transition from breast feeding to eating adult foods in the prehistoric and historic records. Presumably largely from weanling diarrhea. Perhaps something could be added to the diet to get the proper bacteria into the system, such as yoghourt. I would say look to the diet of the adults and ask what is nutritious, what lends itself to a bit of processing, and what can be done to transition the digestive tract into working well with these foods, and experiment from there. I believe that weaning probably did not occur until 2 years of age or more for many groups, so there might be opportunity to encourage going back to this practice and making certain that mothers have adequate diets to sustain quality nursing for 2 years. Hope some of these thoughts help. Perhaps many are things that you have already tried. Regards, Linda Scott Cummings, Ph.D. Paleo Research 15485 W. 44th Ave. Golden, CO 80403 USA (303) 277-9848
