But, can you explain why you have faith in your body? It's not a trick question, I'm really curious. We all die, historically death rates in labour were higher for mother and baby. Diseases spread. Miscarriages occur at alarming rate. Why do we have faith in a body that eventually fails permanently with many small temporary failures in between? Having been a person who has been sick, had miscarriages, infertility, had a complicated birth, fairly extreme BF issues etc, these are all realistic reasons for me to NOT have faith in my body.
I have greater faith in my ability to read my body than in someone who doesn't live in it. My body is not perfect, i have a neuro condition, my feet aren't straight, i have had a miscarriage but i don't feel safe in the current hospital system that they will even listen to my analysis/ponderings of what is happening in my body let alone be more likely to detect an issue than the combination of myself and my midwife who i saw regularly, respected me and was focussed on me.

I also think we come at this from a very different angle on the issue of bodily autonomy v's baby needs. My personal opinion, that I'm not going to lay on anyone else, is that my baby's needs get 100% at any cost at all to my bodily autonomy. That is, if my baby needs it at a cost that is somehow physical for me, I will pay it. I do put the baby's needs at greater importance than my bodily rights. And don't get me wrong, I'm not saying it is impossible to have both (fulfil all of the baby's needs AND retain your bodily autonomy) but if the choice needs to be made, I know which way I am going.
If there is a need to put my child's needs before my own, i also wouldn't hesitate. I don't believe that giving up my autonomy (the right to make decisions for myself) is beneficial to either of us in the long term. Saying that you would pay a physical cost to fulfil your child's needs is not giving up your autonomy because you are the one making the decision. I only have a problem when somebody else tries to remove this decision making ability from a woman.
