No, would never go cold turkey for sure! I totally hear you about giving in and feeding for your sanity and hers - I feel exactly the same. I agree that it's not great to try and resettle them for 2 hrs and hen feed anyway - it's so difficult - you have two voices in your head (at least I do) - one says, feed, they obviously need it (even if it's not for food, but for comfort) and at least you may be able to get back to sleep for 4 hrs or so, but then the other voice says - no, you are accidental parenting, they don't need feeding less than 4 hrs from their last feed, you are going to get into a habit you can't break, you should try and resettle and not give in - etc etc.
DS#1 was a very good sleeper - we had our moments, but he was very easy to fix - when he was having too many NWs to feed, I did PU/PD twice for one night and then he started sleeping through again! Amazing.
I guess we'll see in a weeks time whether this is habit or whether it's a GS or perhaps a tooth will arrive!
I would love to co-sleep if that would improve things - but he will not co-sleep, he just squirms!
I am going to try and early bed again for a few nights - it could be cumulative OT as he's not a great napper (i.e. doesn't take more than 1.5-2hrs total nap per day).
Anyway - thanks for replying and good luck!
