Hi OP, you are definitely not being unreasonable.
I had my baby in May and so many things went wrong due to the negligence of the staff. One of the anaesthetists punctured my spine when administrating an emergency epidural. This led to something called a spinal headache which I needed three surgeries to fix. My baby had got so ill she was going to be moved to intensive care as the midwives weren't helping with feeding even due to my condition (couldn't move my head or neck at all.) The list is actually endless.
I had a debrief meeting with the Consultant that led my pregnancy which was really helpful as he accepted fault on many things and said many things shouldn't have happen.
I had a meeting with the Head of Obstetric Anaesthesia to discuss the spinal puncture and what happened to the Dr who had performed this incorrectly.
I just had a meeting with the Matron of the Postnatal Ward to discuss the treatment of myself and baby once on her ward. A lot of apologies and acknowledgement of neglect and they've shaped how they'll train their staff based on my experience.
My auntie helped me write a very detailed complaint letter to PALS and we are awaiting a written response.
I've been having CBT therapy since July which has really helped me process this traumatic event as I was having nightmares and flashbacks of the ward. It was horrible.
I'm now having a second baby and will be having DC at another hospital as I refuse to go back there. We will soon be filing a case for neglect and will be taking this to the press.
A lot of information there! But I just wanted to show when something goes wrong to the point you're seriously traumatised and scared of having another baby, there's many things you can try and do to feel somewhat in control. I think it brings some sort of closure to hear apologies and accept fault (however in my case this isn't enough as I nearly died and the baby getting ill was avoidable if they had just listened to me.)
Please at the very least, write up a complaint letter and try and have CBT therapy if possible. Those two things will help massively and I'm so sorry for your horrible experience x
