I have no real comment about the picture myself, except that when I first saw it I wondered if the boy was really feeding or just posing. The mom's...assets (must use DIS-unfiltered word) seem a heck of a lot smaller than any of the nursing moms I know.
Now I'll kick into behavioral-ecologist mode:
Now the information I found us about 5 years old but Le Leche League states that the worldwide average for breast feeding is 4.2 years.
If that is indeed true I have to wonder why we as Americans have such a problem with it.
I have no reason to doubt this statistic, as there are many good reasons for extended breastfeeding in many of those under-developed places in the world. Number 1 on the list is birth control. Lactational amenorrhea gives women a natural form of birth control, sometimes for up to 4 years. In countries where women have no access to other birth control methods, long term bf-ing is the best alternative to keep them from being constantly pregnant. Number 2 is poor water sources (and the realted tainting of local food sources). When the water can kill your child (especially in the absence of good medical care), it's best to keep them hooked up to the natural filtration system in your own body as long as possible. Number 3 is lack of available food in general. If you can only afford grain to feed yourself, at least you can "re-use" it to feed your child as well.
American's don't have a problem with extended breastfeeding. We just don't have any
need for it.
Pssst! Animals nurse their young, even those born with a full set of teeth.
Yes, but after a short time period most mammals become lactose intolerant. In fact, lactose intolerance is the base-normal for humans as well. We've only developed lactose tolerance since the development of agriculture (and thus, the taming of milk producing animals). We, like our animal cousins, are not really supposed to continue drinking from our mothers after we have advanced to a level where we can handle solid foods.
That being said, babies (of all mamalian and monotreme species) do not start out drinking milk merely because they're unable to eat solids. They start off drinking milk because that is what they evolved to eat, and what their parents co-evolved to produce. Babies cannot survive (or at least, cannot thrive) on a diet which is made digestible for them, but which otherwise does not contain the same nutrients as milk.
And if I just made anyone google "monotreme", my day is made.
