Good question. When someone is pregnant relaxation and smoothness of flow is appropriate. So when doing Qigong simply slow and easy movements and breath. Nothing too dramatic like breath of fire or challenging Qigong poses for extended periods of time. Everything mindful.
The same is true for a medical Qigong treatment. Very smooth healing sessions – everything calming. You know if a pregnant person is receiving too much energy during a Medical Qigong session when they get stressed and overtly bumpy? Make sure everything is instead is smooth emotional, soft tears is fine. The emotional catharsis that is “bumpy” while pregnant as opposed to smooth is not recommended.
So watching and holding space and if things start building up, the breathing gets heavier or the blood is pumping harder or you see the face getting red then you need to back off and calm everything down down down. Bring energy back to the feet have the person open and close hands. Ground them. Coach them in a normal breathing pattern ” I want you to breathe in through your nose and slowly exhale through your nose and then mouth. Relax everything is ok.”
But if your paying attention there should be no problem. This isn’t going to happen right away..so simply be watchful and work gently and do no harm..
