We stopped before he was 2 but we stopped the falling asleep boob by reading a book then cuddling to sleep (either parent) as he has a big floor bed. The overnight wakes were the last to go but we gradually replaced those with cuddles too.. don't know if you've tried anything else but good luck 🙏🏼
I went cold turkey & the first few nights were HELL. I couldn't cope either, took a few days, really went through some intense tantrums & sleep deprivation, but by the 4th day he gave up. Was happy to cuddle
