Ironically, I have this double standard with myself. I loved that only *I* could give him that, however he wants only *me* to do everything else for him ("No! Mommy do it!"). But I want that time back. It's one of the biggest factors in wanting another baby. I can't imagine never having a baby to nurse again.
So, those of you nursing babies (or kids) savor the moments. And those of you who are so done you're ready to quit, remember this is just a short time in your life, and such an important time in theirs.
