How to get my dog to sleep in his own bed

Context – I had two pugs, and one of my baby’s died around 5 months ago. They both would sleep in the kitchen together however my living dog would no longer settle in the kitchen on his own, I’m talking severe anxiety howling, scratching doors stayed up ALL night until we got him. And it was so sad, so we brought him upstairs, he will sleep in his bed if the TV is on but soon as that TV goes off he’s wanting up on the bed. He will cry ALL night until we pick him up. He’s quite a large pug and wakes us up several times thoughout the night. I’ve tried nightlights, soft music etc but nothing works. I’m now pregnant and he needs to sleep in his own bed. Any suggestions? Is it cruel to just stick him back in the kitchen? I’m happy for him to stay in the room if he sleeps on his own… help please
