Bassinet help! Desperate Mama!

My son is 6 weeks old and has never liked his bassinet or to sleep on his back in general. For the first two weeks of his life my husband and I took turns holding him all night long until we couldn’t stand it another second and broke down and used the recalled Rock N Play which he LOVES!

At his last check up his doctor has encouraged us to start trying to get him to sleep on his back. We’ve started using the bassinet at nap times to slowly get him used to it. But the most I’ve ever gotten him to sleep in it is like 20 minutes. It seems he just wakes himself up after a few minutes.

Please tell me that the struggle is worth it and persistence will pay off!!!!

Any tips or advice greatly appreciated, he doesn’t love to be swaddled. He likes his arm free so I try a kind of bottom half swaddle but it doesn’t do much, I also have a white noise machine that I’m not sure is helping nor hindering.

Please help a tired mama out!!!
