I'd be happy to use EBM if I had a premmie baby because my gut feeling is that they really need it.

And I'd be happy to donate milk.

But I wouldn't be happy to use EBM for a baby that was a few months old. I don't have a good scientific reason for this. Just in my own experience, DD had my EBM for two months (and subsequently formula) and has been to the doctors once in two years. The other babies in Mothers Group who were fully breastfed have been sick way more often so that makes me concerned about using other people's EBM. I know that runs contrary to all the research out there but that has been my experience.

Having said that, I think that Milk Banks are a fantastic idea and I fully support them for people who want to use them. I would be more than happy to donate to them but wouldn't necessarily use their services myself.
