We strongly encourage you to enroll for class before you come. If you do not enroll by creating an account and signing the waiver prior to class, the instructor will ask you to create an account and sign a waiver at class. It is easier to enroll for class during a peaceful naptime/late night feeding than it is when you're distracted by other friends and children.
Also if there are any last minute changes to class (i.e. weather, illness, location, etc.) you will receive an e-mail and/or text message notification to the account you created to let you know of any changes.
