Teaching relaxation techniques is an extremely important part of any childbirth class. Using biodots is one way that childbirth educators can teach relaxation. 
The dots are sensitive to an individual’s body temperature. When a person is stressed then the color is black. However, as one relaxes the color will change to green for normal/calm, and then to blue indicating a peaceful/tranquil state, and also purple for deeply relaxed.
Using the biodot helps expecting moms and their partners evaluate how relaxed they are as they practice techniques such as breathing patterns or visualizations.
Biodots can be purchased through many online sites. We like sixseconds. Their price is reasonable and they ship quickly.
Start using biodots in your childbirth classes, with your doula clients, and with pregnant families that you support.
