Little lady,
why don't you pick a particular day until which you will WIO, and then you can reevaluate? I find it much easier to wait when I know I'm going to have a chance to stop waiting if things are really bad.
If I were you, I'd wait until the cold is gone, then try dropping a nap for at least 3-4 days, then consider sleep training. I'm not someone who is against sleep training in general, but it needs to go together with a good daily schedule for the best results.

unlatching my LO early never, ever worked. We tried the gentle removal NCSS thing for a few weeks and it took dozens of removals each time, and never any less than when we started. That method of night weaning wouldn't be right for us and perhaps it isn't right for you either. What I would do instead is work on the sleep association first. At bedtime, do something else in between nursing and sleep (like reading a book). You can continue nursing during the night if you want, but just try to put him down awake afterward. Once you are confident that he can calm himself and go to sleep without nursing immediately prior, you can start dropping feeds. Good luck
