Sleeep

Hi mamas. My baby is 3 weeks old. Night time is horrid which is to be expected of a new born. But he will only sleep if he’s being held. Every time we lay him down he immediately wakes up and screams. Swaddle, Forget it. He screams being swaddled too. He’s well fed and changed and still, won’t sleep more than 15 minutes unless he’s being held. Any suggestions?!
