I just love these pillow cases! I also bought these inserts to go with them. Every regulation tool can be used for any zone and they can have different effects on each child, but Mermaid Pillows seem to most often help kids who are in the yellow zone and feeling worried, overwhelmed, scared, or frustrated. My patients love to change the sequins so that a pillow is all the same color, make pictures and faces on the pillows, and even use them to make angry faces and then make them fight (which is great for the red zone!).
Here are some more of my favorite Zones of Regulation tools.
