How to get baby to sleep in his own bed?

Michelle • We are due with our first child in Dec and it's a boy!
My son is 3 weeks old and most nights refuses to sleep in his own bed that it next to our bed. He occasionally will, or during the day will sometimes sleep in one of his seats, but usually only wants to sleep while you are holding him. He doesn't like swaddling, he hates having his hands out of commission, I have tried to swaddler with his hands out and while he doesn't mind it, it doesn't help him sleep. Any ideas to help him sleep in his own bed by himself??
