Good luck MrsN 
It's just a question of finding a way to soothe him without feeding. I know some people say you shouldn't have any kind of prop, but from personal experience, it was much easier to find another way of settling him that wasn't boob, then later figure out how to get him to self-soothe. Just holding a hand on his chest and shhhing might help, or heartbeat tapping on his chest if he gets really antsy (this used to work like a dream with DS, now he gets pissed off and bats my hand away. In fact he doesn't like me touching him at all sometimes and tries to prise my fingers off his chest, sneaky wotsit).
Will be thinking positive thoughts for you.
Last night was just so colossally awful here - there was a terrible moment where I thought I might actually smother DS or shake him
the screaming was relentless and nothing I could do would stop it. He eventually went to sleep around 2 or 3 on my chest with me sitting up (much like the early days). I am a broken woman today, so DH has said he will cover the first part of the night if I go to bed now. Just hoping DS's temp doesn't come back up again this evening 
Night everyone, hope it is quiet for you
