I have never cross-nursed but don't think there is anything wrong with it. If another mother needed me to nurse her child once in a while, I would (with her consent obviously), and while I would much rather nurse my own child than have someone else do it, I'd rather my child have donor breastmilk than formula. For those who are worried about what other moms ingest, consider that you don't know what the cows are eating that make the milk that is used for formula either.
They are usually around pesticides, given growth hormones and hormones to prolong lactation, and could be eating their own excrement for all we know. Not to mention the BPA and aluminum from formula cans that seeps into the powder, and well, beetle parts. Breastmilk has the advantage of being "filtered" before baby consumes it, and most medications transfer very little into breastmilk.
The World Health Organization ranks donor breastmilk ahead of infant formula. ETA: From the CDC website: What can happen if someone else's breast milk is given to another child? HIV and other serious infectious diseases can be transmitted through breast milk.
However, the risk of infection from a single bottle of breast milk, even if the mother is HIV positive, is extremely small.
I wouldn't have a problem bfing someone else's child if they could latch on and be comfortable with it (mother and baby), but I wouldn't be comfortable with someone else nursing my child. It's something I feel should be just between myself and baby, but if someone else wants my milks I'll give it up. :D I would probably be okay with giving my child someone else's expressed breast milk, though, as long as I were the one feeding it to her and I knew what the breast milk provider had been up to for the last 24 hours.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
