Most definitely...we drink milk from any old cow so I don't see how it should be any different for babies. It'd have to be somebody I knew well and trusted, I don't think it would ruin the bond I had with my child in the slightest. Much rather breastmilk from another woman than formula. I'd do it for a friend or family member for sure.

I read an article once about a man in some small country town in America whose wife died in childbirth...all the lactating women in the town rallied round, organised a roster and would come and feed his newborn each day and then express for him to feed bub in the evenings. What a lovely thing to do!
