All this makes a lot of sense. My daughter is now about 32 months (age 2.75 or so). And her night nursing has been decreasing very gradually over time. She now nurses only 1-2 times typically during the night, and frankly, I barely notice it anymore. It seems like forever she has been "sleeping through the night," at least for my purposes. I'm happy. We've always co-slept, and she goes right back to sleep after nursing, so it has never bothered me much.
I'd like to say that I've neve done anything in the way of mother-led weaning, but what is more accurate is that I've neve done anything intentional in the way of mother-led weaning. For example, I've never limited her access to nursing, but as she grows older, I have asked her to wait while I go to the bathroom, or rubbed her back for a moment when she wakes at night to see if that will settle her first, and so on. This seems to be happening very naturally, as a natural consequence of our needs gradually shifting. (For example, my need to pee in the middle of the night is often greater than her need to nurse immediately).
I'm sure that my daughter will ultimately wean even if I don't expressly set limits on her nursing. It's clear to me that is where things are heading. The good news is that feels really gentle and gradual, and well, natural. Some of the nursing sessions are being replaced (without us even meaning to) with cuddles and back rubs. The closeness and bond is still there, it's just evolving.
