Tips for getting kiddo to sleep in bassinet

Hi everyone, I have a 5-day-old and I have been sternly told by many folks that I need to get him accustomed to sleeping in the bassinet now or face the consequences later. My wife and I have tried everything; he was delivered 3 weeks early. My wife and I have both been trying our best, but we eventually succumb to the crying, and I either take him and just watch TV and/or stay up while my wife sleeps, and then we switch. I have tried everything in the book, so far: warming the bassinet, sleep machine, swaddling, all of which are to no avail. So I am seeking any tips and advice. Also, I know the whole notion of, “He is seeking warmth and comfort.” I get that and am always happy to hold and have him sleep on me, but I’m just looking to see what has worked for other folks. 

Thank you
