When does milk begin to come after delivery?

I would say that it is a wonder of Nature. Milk begins to come on the second or third day after delivery in case of multipara. Primipara starts supplying milk a little later, i.e., on the third or fourth day. With the passage of days and weeks, the breasts tend to adjust well in their milk production to meet the infant’s needs. This is one unique example of how efficiently nature works. The milk secreted in the first few days is called colostrums (which is milk, as the cynics would have us believe but which is all nonsense). This is exceedingly rich in protein s and gets coagulated spontaneously on standing. Gradually, the protein content falls whereas the fat content shows a rise in colostrum as time passes. In the first month secretion of milk is called intermediate or transitional milk. Thereafter, it is the mature milk which supplies most of the required nutrients with the exception of iron, vitamins C and D and copper. Depending on the demand and health condition of the mother milk production continues even for many years after the birth of the last child. A unique case where a mother continued to have lavish amount of milk even after 30 years after the last childbirth.
