Just to "scratch the surface of the iceberg," here are a few ideas to consider. Prenatal Yoga is a specialist's field. Just because you briefly covered it in a level 1 Yoga teacher training, does not mean you should enter this field without a specialist education and certification in Prenatal Yoga. Each trimester is handled differently. The first trimester can be as dangerous as the third trimester, if a student is not receiving specialized Prenatal Yoga instruction. The last trimester is similar to Chair Yoga, but that does not qualify a Chair Yoga instructor to work with pregnant students.
