I weaned 2 kids while pg, b/c my nipples were so sore. However I held out til the 8th month both times! Then I was so huge and uncomfortable one more discomfort was too much to bear.
Many women wean during pregnancy b/c of pain. Many babies wean when mom is pg b/c they don't like the change in milk taste/quantity.
With my 3rd and last, he nursed longer than the other 2 (each child nursed a yr longer than the previous). By the time he was 4 1/2 I let go of my goal to do child led weaning. By negotiation and his choice/need, we were down to only one 2 minute nursing at bedtime after stories. He would nurse, roll over and go to sleep. I know he could fall asleep without it, as just my presence next to him was enough comfort. So we talked it over, he agreed, and we weaned with no regrets on either side.
I am really glad I nursed him that long. He has been by far, my healthiest child. Well, no vaxes helped too!
He is proud he nursed that long too! He is almost 13 and b/c of my volunteer work, I never let him forget it. heh
