milk is complete food.

i do not agree. when the lactating mother provides milk like breast milk feeding, it is not painful for mother, it is pride of mother, she pours the milk with affection after the breast feeding her weight not losses. like wise if she does not feed the breast feeding, she feels pains and it requires feeding. like wise the cows, buffaloes  , goats give milk  happily,
 secondly what we eat and drink in converts to first in to blood during that course of time it , the milk is the bye products of our food, blood converts flesh, fat, bones, bone marrow and then semen . it is based on AYURVEDA, SO milk is the product of affinity and secretion of glands . so milk is useful and complete food. when we were born taken breast feeding of our mothers.
