I just talked with my mom about this. I was born in 1973 and my mom nursed me for 6 months. My grandmother was very supportive of her wanting to nurse me, because she had nursed my mother and my aunt back in the 1940s and was quite pleased to her my mother's decision to nurse.
Not only that, but she said she got interested in nursing, because of some positive episodes on the benefits of nursing Phil Donahue had done on his talk show. She decided it made a lot of sense and must be the best thing for babies.
When my sister was born in 1981 she nursed her well over 1 year. Mom said she was mainly motivated to do this, because of not wanting to give sister a bottle. Apparently I got attached to my bottle, so mom got smart and went right to the sippy cup with sis.
She always talks about how wonderful it was and how important it is for bonding.
Mom, also, was very passionate about natural birthing. She's never heard of the term AP, but she used a lot of the philosophies raising us. I'm truly grateful for all her support. She seems to agree with a lot of my ideas about raising my children. Or maybe I just learned it from her example
