I haven't heard of anyone who has, but if I remember correctly, a breastfeeding coach once told me that she had helped a mother breastfeed a child she adopted so anything's possible!!!
You can search for Breastfeeding Pinays page..there you can read many things about bfeeding and they also have some events for lactation etc...
i've heard of stories of relactation. but i dont know anyone personally. but i would like to commend you for taking the initiative!
