Jumping in here a bit late (and haven't read all the responses but plan to go back and read). How I wish I would have had a forum like this when my LO was a toddler all-day, all-night nurser!! Fast forward to 10 years later and I have what I consider a more typical toddler nursling. My second LO was really receptive to the "don't ask, don't refuse" idea - probably because I was offering way more than I realized. Although I am totally supportive of CLW and on some level wish that was something that would work for me, we are on the road to parent-led weaning. We did a month of "don't ask, don't refuse" and are now doing a bit or distraction and offering food before the breast. I'm also having a lot of success with "Boobies go night-night" and have night nursing down to twox/night and one session at daybreak.
Ok... I hope that doesn't sound like I've figured something out. I feel as thought I am a fairly similar mother to this easily weaned (so far) LO as I was to my first who was to my first who was an absolute breast fiend all day - seriously like 50 times a day nurser. If I had more support I feel really strongly that my first was a good candidate for CLW or quite a bit more time unrestricted at the breast because weaning her was really hard. This was a "when you know better you do better".
Anyway, I sympathize and totally remember those days and feel like that's just how some kids are at that age. From my experience with my two kids, one was ready for some gentle parent-led weaning steps by around 2 and the other was most certainly not.
