It's very easy to obtain a certificate and do nothing more for the rest of your baby massage career and just continue teach- teaching the same information with each session you teach to families.

This is where your classes and what you teach becomes stagnant. You'll be teaching from a place of muscle memory and not from a place of continuous learning/education.

By immsering yourself in additional training/studying is going to be so beneficial and conducive to not only your practice but to families who come through your doors.
