I am a hypnobirthing coach and doula and I do one to one sessions where I explore with the mom to be, what techniques and methods might work.. we try out a few things .. then I record individual relaxations. There are many approaches to this type of practice, some work better than others for individuals. Getting to know how the individual responds to specific words and different techniques means that I can tailor the recordings to them.
Some people find the techniques useful in many different scenarios and indeed, this approach to stressful situations can be hugely beneficial.
Many people find the generic affirmations / visualisations / recordings great.. but for many others, there are words, images, suggestions, that have a negative association and are therefore not helpful. Some people like music, others like guided breathing, progressive relaxation, guided muscle relaxation, visualisation.. there are many options. For some... imagining being on a beach makes them think of sunburn and scratchy sand and the most relaxing place for them is imagining they are at home, snuggled up on their sofa!
'My baby will be born safely' 'I trust the people around me to keep me and my babh safe' 'I am safe', 'My baby is safe'
We can increase our heart rate and rate of breathing by thinking of difficult and stressful things and we can reduce them by reminding our mind and our body that we are in good hands... that soon we will meet our baby...
The practice of bringing your body and mind into a state of conscious rest and relaxation, regularly, is beneficial and makes it easier to return to this state, when faced with stressful situations. Remaining calm in stressful situations helps us to make better decisions and improves outcomes both in the short term and in the long term.
You are not lying to yourself or silencing your valid concerns, you are putting yourself in the statistical likelihod of a positive outcome and putting your trust in the expertise and experience of your medical team. For some that is about not considering possible outcomes, for others it is focussing on the vast majority of positive outcomes.. we don't get into a car thinking we might scratch it.. we trust that most times we drive, will be without incident and if there is something, we will be able to deal with whatever comes.
I hope.you find an approach that works for you.
