You may take Hypnobabies classes at any time prior to giving birth provided you start the program 6 weeks or more before your estimated due date. Keep in mind that once you finish the course you will need to continue to maintain your hypnosis techniques through daily practice. If you choose to take the course early in your pregnancy, realize that you still must commit to practicing every day until the baby comes. Many women find that starting their Hypnobabies classes around 30-32 weeks.
