The gradualism ‘argument’ does not work because until the breast works, it doesn’t work, and therefore confers no selective benefits. As Uncle Charley wrote, any variation which does not confer immediate selective benefit is a waste of space and will be ruthlessly eliminated by natural selection. So the offspring could not have survived while breastfeeding was in development but not yet functioning, even if there were any reason for supposing such a development, which there isn't apart from evolutionist fundamentalism. Therefore no such evolution could have occurred.
According to a Darwinian view of how natural selection works, and I have studied and understood 'Origin of Species', babies could not have developed the ability to flourish on breast milk before it became available, there could be no selective reason for them to do so. Yet the mother's ability to produce it could not have been selected for until the baby had developed the ability to utilise it effectively. It simply doesn't work, even if we very generously allow the possibility of the DNA information for both breasts and a baby that can use them developing by random mutations. which given what we know about random mutations and the breast (Google mutation + BRCA + breast cancer to see what random mutation does to breasts) is being much too generous.
