8 week old not sleeping no matter what I do

My LO just hit 2 months old and the sleep situation is not getting any better. We start her bedtime routine at 8 and she’s usually out no later than 10. We will get her laid down in her bassinet. Usually wakes up at 12, either I have to nurse her or sometimes can shush and pat her back to sleep. Then it never fails she’s up at 2 am again, demanding to be fed. I will nurse her and hold her upright for 20 mins (due to reflux) lay her back down, and she’s up 30 mins later. This will continue until I get us up for the day.
What am I doing wrong? I make sure she’s getting a FULL feeding each time, and she’s getting a good calorie intake during the day. I follow her wake windows as best as I can, and contact nap during the day so she gets some sleep (naps are a whole other story. Cannot get her to nap anywhere but on me) which I could live with if she let me sleep longer than 1.5 hours at night 🙃
Any tips, insight, advice? Or did I just get a baby who hates sleep and only wants to eat? I’m having a hard time seeing the light at the end of the tunnel
