Sleeping issues!!

So my man is 3 weeks old and from last 3 nights, he is not sleeping in his crib at all. He is absolutely fine in day time, I put him in crib and fall asleep on his own, no help needed.

Evenings he started cluster feeding around 8 to 11. Then I try to make him sleep in crib but no luck, he cry everytime. Then finally he fall asleep in my bed and he sleep 4 hrs. Wake up once in whole night. But I’m sleep deprived :(

I’m very very lite sleeper, unable to sleep when he is on my bed(for obvious reasons)

I have no idea, why he is doing that.

Mommies please help if you have any idea to make him sleep in his crib.

Thanks!!!
