Safe Sleep Advice

I seriously need some advice on how to practice safe sleep with my child. He is 3 weeks old and he just will not sleep in his bassinet or playpen for more than 5 minutes. I am terrified of SIDS so I refuse to bed share.. But he won’t sleep unless one of us is holding him. Currently, my husband and I take turns sleeping on the couch with the baby on our chest all night.

For those of you actually practice safe sleep, please tell me what you are doing that works. I feel like I tried everything- swaddling, making sure he is fed, waiting until he is drowsy before putting him down. Nothing is working for me.

Please help this tired mama out.
