Baby won’t stay asleep!

I have a sweet 2 month old baby girl who just wont stay asleep! She will fall asleep in my (or my husbands) arms and then we put her down in her bassinet, wait a few minutes and then leave as she’s sleeping, but then she will wake up 10 min later. Us putting her down for the night right now is 3 hours of her sleeping in segments and then needing to be attended to. We have tried swaddling her, feeding her (she is currently bottle fed strictly breast milk - I wasn’t able to nurse but I pump exclusively), putting her binky back in her mouth, putting her on her side, white noise machines, we’ve tried staying in the room for longer.

She’s not getting good sleep and then she’s cranky and overtired, which makes her not sleep more!!! Does anyone have any advice on how to get her to stay asleep longer?
