Author's Note 15
The ancient Peruvians wrapped their children in loose swaddling bands, leaving the arms quite free. Later they placed them unswaddled in a hole in the ground, lined with cloths, so that the lower part of the body was in the hole, and their arms were free and they could move the head and bend the body at will without falling or hurting themselves. When they began to walk they were enticed to come to the breast. The little negroes are often in a position much more difficult for sucking. They cling to the mother's hip, and cling so tightly that the mother's arm is often not needed to support them. They clasp the breast with their hand and continue sucking while their mother goes on with her ordinary work. These children begin to walk at two months, or rather to crawl. Later on they can run on all fours almost as well as on their feet." Buffon.
M. Buffon might also have quoted the example of England, where the senseless and barbarous swaddling clothes have become almost obsolete. See also la Loubere,Cf. Le Longue Voyage de Siam, Le Beau Voyage de Canada, etc. I would fill twenty pages of citations if I needed to confirmer all this with facts.
