My girl's bed has 4 pillows, in different sizes. One is for her to put on top of her head and another for her head while other 2 are just scattered around her bed.
While our bed is pack with at least 4 -5 pillows and every day we would wake up with one or 2 pillows on the floor. Luckily we do not have bolsters otherwise more stuff in the beds. Sometimes I wonder how we sleep with all those stuff around. Lol!
