Why won’t my 7 wk old sleep?? Help!

I am going crazy trying to get my 7wk old to sleep at night. Falling asleep is never a problem but he gets up every 1-2 hours gets a bottle and then back to sleep. I have tried so many “tips” and every night it’s like a cruel joke that there’s no improvement in his sleeping. The most he will sleep is maybe 3hrs and that usually if I’m holding him in our big recliner.

Swaddling doesn’t work because he doesn’t like his hands confined.

I have an air purifier by his crib for white noise

I made sure he doesn’t nap more than 2hrs (at a time) between 7-7

I increase his bottles from 2-3oz to 4oz at night while giving him an extra bottle while he sleeps to keep him full longer. (He actually woke up an hour later and drank 2 more oz)

I make sure the room isn’t too hot or cold

I try to nurse him at night because that worked best with my first but this one still isn’t great at it. Will nurse for only a min or two or refuse all together.

I even tried giving him formula at night to keep him full with no improvement.

I really am at a loss. He’s great during the day but at night it just doesn’t make sense how frequent he gets up.

Edit: sorry I didn’t mean he only naps 2hrs for whole day. I meant I don’t let any of his naps last more than 2hrs
