I have never seen one piece of evidence that links breast size to either
amount or quality of milk, either. The "something to hold on to"
speculations are utterly without foundation. At one time I speculated
(1974) that the human female breast evolved its larger size to provide the
infant with a soft and glaborous surface, that was giving, and that it had
an important role to play in the dyadic relationship that develops between
mother and child, somehow relating to extended nurturance. That too is
simply a lot of speculation. Maybe the female breast has multiple
functions, and that sexual attraction and signalling is one important
aspect of that total function, with more importance than as any sort of
augmentation of milk.
