Michael, women can relactate at any age. Women who adopt babies can produce mil, even if they've never had a biological child. And if they don't, there is more to breastfeeding than just milk - so it's still worth while.

Barb, I stand corrected.

I think what I was getting at is that I've heard that up until 6 months, the process is considerably easier. But of course, you are right, I have heard of women who have adopted a baby and have lactated.
