Toddler repeatedly getting out of bed

[Endofmytethertoday]

My 2 year old has been in a proper bed for around a month, has always settled well in his cot and sleeps well but is taking around and hour/hour and a half of repeatedly getting out of bed and shouting in the landing before he settles to sleep. We've tried ignoring, we've tried just walking him back to bed each time without any interaction, we've tried making bed time a bit longer with longer cuddles etc, we've tried sticker charts. We've tried nightlight/no nightlight, books for him to look at after we've left the room, he's got cuddly toys in his bed with him.
He's usually out of his bed by the time we've got downstairs after putting him down. He is so tired, he's miserable and ends up napping whenever we're in the car which I think is only going to make the problem worse! I'm at the end of my tether, I'm fed up of spending my evening going up and down the stairs and there ends up being very little evening left by the end of it!
I don't know what else to do, any suggestions?!

Sit in his room until he falls asleep? Or sit on the landing?
Thats what we had to do with my daughter, just sat and ignored until she fell asleep but it stopped her getting out of bed. Then I’ve transitioned to sitting on the landing, then I just go and sit on our bed and watch the monitor until she falls asleep - she thinks I’m on the landing right by her door. I’ve only had one night where she got out of bed but by the time she got to her door I was there to put her back.
Agree about as little interaction as possible otherwise they think it’s a game. It will pass, it’s always a phase, it doesn’t last forever (is what I constantly tell myself!). Wishing you luck!

Try a bed rail?

Other than that I’d agree with the PP above. And it will pass.

Stairgate on the door?

Do you read to him at night? We stopped tv before bed so DC was not stimulated and instead read about 5 books which made her really sleepy!
