Personally, I don't think it's wise to night wean a toddler because it can be so traumatic on them. There are so few things that truly comfort a toddler, taking away something so important to them leaves you with an empty toolbox. Imagine nightweaning and suddenly having a crying baby who won't calm because they can't nurse. It's not like the nightwaking is really going to go away just because they're not nursing. It does for some, but not the majority of people I know who have nightweaned before their child was ready. So, now you have a wide awake baby that you can't nurse back to sleep, and wants to P-A-R-T-Y!
In my experience, whenever I've had those thoughts, it's at the peak of my exhaustion and frustration with the situation. Somehow, things seem to get bad, then worse, and finally unbearable and then like magic, they suddenly get better. Hang in there, it might be getting better really soon.
