Wet Nursing making a comeback

I ran across this article about wet nursing in J's Time Magazine. If I've run out of reading material I'll pick up his Time or if something on the cover catches my eye. Well, this issue was about the massacre at VTech so I started reading and finally landed on Milk Maid. It seems wet nursing is making a minor comeback. And not only that, some mothers are sharing milk. For instance, if my friend and I have babies at the same time we can share our nursing responsibilites between us. Blah. I think it all sounds more than a little bit freaky.
