Hi
I weaned both of mine off night feeds a little younger- about 9-10mo & used different approaches with both.
My DD actually dropped some feeds herself and then I just held out on feeding until the last feeds pushed later and later and finally became morning feeds.
My DS refused to go back to sleep without the feed so with him I timed how long the feed took and gradually reduced how long I fed him for by a minute every 2-3 nights. I weaned one feed at a time until he was going without.
I have seen others with older LOs (over 12mo) just going "cold turkey" though and only offering water but no BF.
Sending your OH in for the NWs (if that's possible) can also work if you want to go "cold turkey"
With teething...I think once you drop NFs, it is confusing to restart and can re--establish them, and then you have to go through weaning off again. At least by 14mo, you probavky only have one or 2 more sets of teething to go (1&2yo molars) so hopefully could medicate and cuddle through when it happens?
