As for the colostrum, pumping colostrum is very hard, and some women even have a hard time expressing it by hand, so even if baby is getting plenty, it would be easy for an uninformed mama guided by clueless health professionals to conclude she hasn't got any. The quantity produced is so small, and that's good and normal and natural, but a lot of people don't know that.
As for the milk-- even if you never, ever put baby to the breast, milk will still come in. I lost a baby early in the second trimester, and my milk came in. It won't stay, but it will come. Likely her milk took a long time coming in, and didn't result in engorgement when it did come, and because she never nursed, it didn't stick around very long. My milk takes a long time to come-- five or six days each time-- and I only got engorged the last time. So I can see again that an uninformed mama would conclude she hasn't got any.
I guess that theoretically some women would make none at all, but they'd have markedly underdeveloped breasts, wouldn't they? Even mamas with inadequate glandular tissue usually make SOME milk.
Sounds like the usual hooey to me.
