Need help - won't stop o/night feeds

My DS is 2 & a bit, and has a morning and an evening BF, and most nights an overnight feeding frenzy at about 3am. I'm happy to keep the morning & evening, but now that I'm pg (well, even before I was, but it's even harder now), the overnight session is just pushing me to breaking point. Plus it hurts, as my bbs are so tender:redface: And selfishly, I'd kind of like a few months of no overnights until bubs comes along & it all starts again.

We have tried just sending DH in, but this generally means he's up for about 90 minutes while DS screams the house down until he's too exhausted and collapses, but then DS will generally be awake again in an hour or so, and the session starts again. Or I give in and go in, on the nights when DH doesn't cope so well with him.

If I get up, he basically rips my pyjamas off to get to the milk. He gets himself worked up into such an angry state until he gets what he wants if I tell him "no, it's just cuddles", just fights and scratches, kicks, all those delightful things that 2yos can do (I know- I'm being beaten by a 2yo!).

I'm at the point where I just don't know what to do to stop it, and with the "delights" of early pg, I'm not coping as well as I normally would. So if anyone has any ideas or suggestion, no matter how crazy, please share :), cos I reckon I'll just about try anything

I'm not sure I have any helpful advice as I night weaned DS at 14 months. His reaction was much the same.
Maybe at his age you need to create a narrative that you can use to explain the change and work through together to ultimate weaning. Like a countdown to when he's a big brother with no night booby or something along those lines.
Have you read Pantley's No cry sleep solution books? She has one for toddlers that might have helpful suggestions.
Good luck
