There isn't a single hypnobirthing technique that isn't a skill for life. So I encourage you, pregnant or not, the next time you notice you're having the urge to change what is, wishing for the future or yearning for the past, bring your attention to accepting the moment for what it is. Breathe out resistance and notice how much easier things feel. It works.
One of the biggest misconceptions about hypnobirthing is that, it's all about having babies. Women have heard that if you do everything your teacher tells you to do, you will have a quick, straight forward, pain free, vaginal birth. Now, there's no easy way to say this...but that's all pretty much a nonsense.
