VilhjalmurStefansson talks of the feeding of Inuit infants and children in
several of his books.  Their traditional children's food was fish-head soup.
The heads of Arctic fish have large fat deposits so this food is very
caloriticly dense.  My own son Gray-Hawk (now 5) weaned himself after his
first year and would eat almost nothing but pemmican for about a year after
that.

New cheaper sources of animal fat and protein would have to be found to make
such foods available to third world children.  New methods of vacuum
harvesting of termite mounds may make this possible.  It has been estimated
that there are about 900 lbs. ( 400 Kilos) of termites for every human on
earth.
