My 27-month-old daughter is still nursing, probably about 3-4 times/day. But her morning session usually lasts 30-45 minutes, and the others are anywhere from 5-30 minutes apiece. Aside from the major breast and nipple tenderness, I love nursing still. I don't have that skin-crawling, get-her-off-me feeling I've heard some mamas get, and my supply seems to be good still, so I'm just going to go with it. I hope it stops hurting after the first trimester, though!
