I come from one of those rare and abnormal families where EVERYONE BF (we also all used cloth diapers, even in the 1990's when you could easeily get spoies).
My great grandmother did, and her daughters did as did my mom. Same on my dad's side. All my aunts did as well. We were rural farmer people, so I wonder sometimes if that was why (after all, the momma cow feeds her babies, right?) Generally we were all weaned by 10 or 11 months because as my mother said: I had to many things to get done rather than to sit and nurse!
My DH's mother was very urban, wanted to be very hip, talks about always doing the latest thing (she has redecorated her bathroom twice in our 5 years of marraige). One time she didn't bath his sister in 1958 for a few weeks because they told her all she needed to do was clean the baby with baby oil! Anyway - she FF all of her kids and said with my Dh, who was an accident and came much later in 1974 she said she got the "Milk shot" so her milk would dry up, but she still had it. So the Dr told her to try and nurse!?! So she nursed DH for about 3 or 4 months.
So guess who is supportive of me nursing past 6 months.
Uh - not my mother! I think in her day it was a sign you were poor, which is one of the reasons she did it, so she is very much against it! DH's mother and family are supportive. (Its about the ONLY thing they are supportive about... but that is a whole nother thread
: ) It is hip now again - so Dh's mother is all about that.
