Baby doesn’t sleep at night.

My baby is now 6 days old. For the past couple of nights he has screamed the whole night with maybe an interval of 20-30 min of silence after eating. We’ve tried bassinet, rock and play, and a co sleeper device that sits next to us in bed and he willl not stop screaming! We’ve also changed him, fed him on his schedule, given him pacifier, changed his outfits, wiped him down with a wash cloth, put lotion on him, gave him gas medicine and made sure he’s swaddled and covered comfortably.

What else can we possibly do? Me and my husband are running on 3 hours of sleep a night right now and it’s miserable. My husband is leaving for work at the end of this week and I’m terrified of dealing with this all night by myself!!

Any suggestions we haven’t already tried??
