Through so much research (I really should think about getting paid for all that I do! haha) I found out that women can actually generate breast milk and therefore breastfeed a child even if they did not birth one.
S. and I are actually really excited at the thought of being able to breastfeed our baby as it will create a great bonding experience for us. (Not to mention the great health benefits derived from breastfeeding.)
I plan on switching to an all-Japanese food diet once we get our call to travel and will be taking the natural herbs and supplements to try and generate breast milk. All I can do is hope that all goes well.
