Hmm. I just read someone's blog and it made me think of silly stuff. Though my nephew mistook my breasts as operational a few times during the night (don't worry, folks...I removed him and explained that mine just didn't work in that fashion at the moment), I have no idea what it's like to give nourishment born of my body.
I suppose if I ever get around to getting married and having children, I'll look more fully into the matter. Breastfeeding is highly beneficial to both the child and the mother. Babies who breastfeed tend to have better health and whatnot while the mothers lose their "baby fat" due to the loss of "extra" calories. Also, I've heard that it's supposed to create a bond. Having no experience in the quarter, I can't confirm or deny. I can, however, assert that my newphew and I bonded just fine and with the exception of his few failed attempts, I didn't breastfeed him.
If I ever go off the deep end and just randomly ask someone to suckle at my breasts, I'll keep you informed.
