Baby does not stay asleep!! HELP

Nael • @InThaCutz 💚

Hi mamas. My LO was born on 6/15. We are currently facing some difficulties putting him to sleep. Last night he was up from around 12am until 6pm the next day with only some naps in between which only lasted between 5-20 minutes max. I called my advice nurse and they said this is okay as long as baby is eating, not crying as if he is in pain and pooping/peeing as usual. BUT I am one tired mama.. I just want a break to close my eyes for a little.. I have not had any caffeine that could possibly interrupt his sleep.. I've tried taking him on a walk in his stroller.. rocking him, bouncing him, having him fall asleep laying down next to my boob, on my chest.. tried giving him a bottle with chamomile , formula made with lettuce tea, lettuce under his pillow, I feel like I have almost tried it all.. but little one does not seem to give in. Just right now he woke up from a 38 minute nap which is glorious! I took advantage to go shower. Mamas help please!!! Has anyone gone through anything like this? How did you get baby to finally sleep!!!???? He is only 7 weeks and a couple days.. he should be sleeping more than this
