I follow what I called child-respected weaning.
I didn't do "don't ask, don't refuse" with either.
With my son, who weaned a month shy of 5 years old, I refused many, many times every single day. He wanted to nurse 24/7. I needed a nursing amount that I could handle. It's because I set limits that I was able to nurse him for so long. He always nursed far more than the norm. You do what you can handle and repect what your child needs.
With my daughter, who is still nursing at 2.5 years old, I offer many times. She will only nurse at night and only lying down. She does ask for it now. But there was a time when she wouldn't ask for it at all.
I didn't do pure CLW with my son, since I did cut him down every step of the way. But I know I had to in order to keep my sanity! Plus, I don't know of any kids who wanted to nurse as much as he did. It definatly wasn't the norm.
So far, I am doing CLW with my daughter, but she's the one who has been pretty much textbook on her nursing. At 2.5, she nurses 3-4 times a night now, which isn't all that much IMO compared to how much my son wanted to nurse.
Though I post on this forum, pure CLW isn't my goal - Child respected weaning is. (But it's hard to find people who nursed an almost 5 year old who didn't do CLW).
