2 year old son screams ‘mummy, mummy, mummy’ every night - what can I do about it dads?

Bit of backstory: he’s 2 years and 2 months, for the first almost 2 years of his life he’s co-slept with my wife and he’s still breastfed. On average he’d wake up somewhere between 6 & 10 times every single night. I kept asking to swap and eventually we booked my wife into a hotel, got our 4 year old to sleep over grandparents, and I looked after the little guy - it went fine!

But now, after 3 or 4 months of me putting him to bed, down for naps, and me exclusively settling him at night, for the past few days he’s massively upped the ante and is just screaming constantly until he can see my wife. Keeping him in bed is impossible, I’m sleeping next to him and at times almost having to wrestle him as he screams at the top of his lungs. It’s honestly awful.

I’m trying desperately to protect my wife’s sleep (the other night she got a solid 8 hours for the first time in three years) and this feels like such a huge setback. I have no idea what to do, singing to him, stroking him, cuddling him, ignoring him, it doesn’t matter, he’ll just scream at the top of his lungs for mummy. Not trying to be a jerk but part of me also feels like he’s kinda too old for this now? 😅 I know you shouldn’t compare, but our 4 year old was not at all like this. But he also wasn’t breastfed beyond just a couple of months due to a tongue tie.

Would really appreciate any suggestions or advice please, currently trying to put him down for his nap and we’ve had 20 minutes of screaming & crying for mummy, even though he knows she isn’t in the house. Thanks
