i currently have four, one under my head and three other pillows. i usually only hold two (one between my legs and one between my arms, i sleep on my side) but one is a little smaller so i can adjust my sleeping position. if you cant tell, yes i move heaps in my sleep and need an insane amount of support to calm my anxiety lol.ni also have a few plushies including a squishmallow.
One under my head and two next to me bc I have a big bed and extra pillows for naps and/or if I want to spread out. I also have a neck pillow and decorative pillow…so maybe five? lol
I keep two on my bed, but I only use one at a time. If one pillow feels uncomfortable and flipping it around doesn't help then I swap it out for the other pillow.
