Its tricky. Mine did a good job of talking about medical interventions, why they may be needed and what could be done to ensure you still felt in control and informed.
Its finding a balance because I found the crunchy stuff a refreshing change from the constant, "its awful, you just have to suffer" "No medals, get an epidural", horror story after horror story. These stories are so important, we shouldn't go into it naive but I had such a scared and negative outlook.
In the end I did love my birth. Back to back baby but water birth with gas and air. A large, large part of that was pure damn luck but I felt informed, I knew what was going on, I didn't panic, I was able to advocate for myself and my husband had tools to support me. Im genuinely looking forward to doing it again.
The biggest factor though was my incredible midwife who was experienced, calm and confident. When she thought the baby was in a bad position a week earlier she had no problem talking to me about c sections, she wasnt evangelical and it was continuity of care so she knew me.
Charities, these groups are a red herring, we should be able to look and find support as we want. What we need is to support our midwives. Pay them properly, work life balance to encourage more into the field, free training and ongoing professional development. That's whatll make the difference.
