My baby doesn't like sleeping on his back....

Angel

My babyboy is 6weeks old, recently he will sleep from midnight to 5-6am on good nights but during the day is mostly wake unless he's in the car or carriage. My baby doesn't sleep long at alllll on his back to me he loves to be enclined but I don't know if this is safe or good for him. I have tried everything, I swaddle him but the only time he will REMIAN in the swaddle is during the middle of the night. Ladies any advice for me......
