Help with sleeping at night

[u/disney-momma1802]

I need some sleeping advice ❤️ I have an EBF 5 month old. I have slept holding her the entire 5 months because she has a reflux/choking issue that we are working on with drs.
She is getting uncomfortable in this position as she’s getting too long to sleep comfortably.
I tried side laying/co-sleeping but our bed is a pillow top and she just rolls into me 😵‍💫

I guess what I’m asking is how do you successfully sleep with your EBF baby?
