NEWBORN NOT SLEEPING

Please help!

FTM here, and I could really use all the help I can get!😭

I know newborns are suppose to sleep around 15-18 hrs in 24 hrs lately my 1 month old has been fighting his sleep! Right now the most he sleeps is 12 hours or less. He does have gas from what I can tell he arches his back and sometimes wakes up trying to push the gas out and succeeds at it sometimes. We burp every 2oz he usually drinks 4oz. I guess what I’m trying to ask here is what am I doing wrong 😭 I don’t understand why he isn’t sleeping and I feel terrible about it
