Well...i have one yes, one no, lol.
i had started VERY gently limiting dd as we approached 2 yo...just making her wait a minute or two, as opposed to jumping every time she wanted milk, not by any means curtailing it more than 10% or so, and then one day, right at her 2nd birthday, we went to bed........and woke up..the NEXT MORNING! I was engorged, lol, but it was our first full nights sleep in 2 years. there were a few weeks of occasional nightwaking, but pretty much, it was sleep straight through the night for us after that..my boobs adjusted to not nursing at night, and we continued to nurse during the day for 6 more months.
Withe ds, I was really not wanting to nurse as much anymore, so at 18 months, i started weaning, general weaning, not specifically nightweaning....and cut the nursing about in half over the course of a couple months....and during that pocess, he started sleeping longer...which meant waking only 1-3 times per night instead of 4-6. And then he stopped nursing altogether. It was almost as if he said "well, if you aren't going to give it to me EVERY time i ask, then i don't want any at all, so THERE!" So, a couple months shy of 2, we were completely weaned, and he did wake at night for a while, and i gave him a sippy, and now he mostly doesn't wake at all, and he'll be 2 in a couple weeks.
