I weaned DD about 1 1/2 months ago. I was really surprised, it went fairly smooth. She made it easy for me though, by basically self weaning during the day.... Night time was a little harder though. I started by changing her night schedule, moving the feeding to the very beginning and waking her back up for everything else. Then after a couple weeks of no daytime feeds I figured enough was enough. We'd already worked on night weaning, so she wasn't nursing during the night, so I just dropped the bed time feeding and did the rest of the routine. At first DD wasn't thrilled with it, but after a couple nights it was like my boobies didn't exist anymore.

What I ended up doing for the night time feeds (not bedtime but middle of the night ones that make it so you don't get sleep) was using a slow extinguishing method that works great for nursing toddlers. You pick an eight hour block of time that is the most important for you to sleep during. Then, during this time: first three nights, pick them up and nurse them for a minute, then pluck them off before they go to sleep, rock them to sleep, and put them back down. Second three nights, pick them up and just rock them to sleep. After the second three nights, you don't pick them up anymore. You can sing to them, scratch their backs, hold their hands, whatever you want to do just don't pick them up. The first few nights are tough because they are so used to being held and cuddled back to sleep but soon enough they recognize that you are there to comfort them still. (The first night we did this there was one time it took DD 90 minutes to go back to sleep, thank goodness it has never been close to that long since). Pretty soon the toddler will start sleeping through the eight hour block, maybe even longer. During times outside of the block you will feed when they demand it though. I know it seems strange to think that one time block will always be consistent from a different time block but trust me, the baby knows when it's 8-12 and not 12-8.... DD is like clockwork now, and routinely sleeps 12 hours at night, sometimes she will wake up once and we will have to rub her back for a minute but she always goes right back to sleep... She sleeps WAY better than all my friend's babies that did CIO or ferber too...

Also this method works if you are still cosleeping too.

I haven't heard about it being dangerous, but it is exhausting because both are nutrition and calorie drainers! Once you're pregnant again, it's a good time to wean because of that (and you might not want to nurse two once baby comes, although I've heard that some women have). However, toddlers do get nutritional benefits from continuing to nurse so don't buy into the myth that it's just a psychological benefit or just for moms who 'can't let go'. The current recommendation is to nurse up to 2 years and the average age for weaning around the world is between 3 and 4 years. However, your toddler does have plenty of other nutritional options at this point and baby doesn't. I think it would be a good idea to check with your dr, make sure you're gaining the weight you should and you're not overdoing it. Just don't be too hard on yourself if you need to wean. Your toddler might not like it at first, but she wont be scarred for life and I'm sure you'll find other ways to bond with her. Good luck! :)
