My 21 month old is in a sleep regression. He has a hard time falling asleep. Should we wait until he runs out of energy or what?

He’s absolutely wired even with a bedtime routine.

If we let him stay up he will be up really late.

If not we end up rocking him while he squirms for hours. Same with in the middle of the night. I don’t see the point in fighting him to sleep if he’s just going to be awake anyways.

He just gets out of his room if he wakes up. It’s a safe space with toys but doesn’t care he just wants out of the room.

He will scream if he’s kept inside it so the only thing that works is to have him fall completely sleep… by rocking him 😩 it’s the only way he falls asleep now when he used to put himself to sleep just fine. It’s been a week and I was awake for 5 hours last night with him. He shares a room with his older brother so he can’t be screaming all night and waking him up too.

I’m so stressed and I can’t rock an almost two year old to bed my body can’t take it. What do I do:(?
