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. To disinfect them I switch the sequins all in one direction, spray it with a few squirts of Cavicide, let them sit for 3 minutes, then switch them all into the other direction, spray them again, and let them sit again. It takes them overnight to dry (even with our dry desert climate) so only 2 patients can use them each day, but I’m limiting myself to only 2 in-person appointments each day right so it works with my caseload. Once the pandemic is over I plan to disinfect them using these steps on a monthly basis.
