I need sleep!!

The past 2 nights have been absolutely horrible. We dealt with reflux for a little while and we found a solution to that but now she won’t sleep at night. Like literally stares at the ceiling, is fussy, or wants to be fed. I would say she has her days and nights mixed up but I have been very diligent about not letting that happen. She naps in a bouncer or in our arms with all the blinds open and only sleeps in the bassinet at night. I would say she is cluster feeding but she spits up what she eats between her normal feedings. I need sleep please help!! I go back to work in a month and hubby goes back Monday and we can’t stay up all night.
