Please do take this on. In my single experience, postnatal care completely ignored my very real medical needs, and from support and advice I've received on MN as well as general discussions I've read, I doubt I've been the only one.
I would like to see women who have had traumatic births and additional complications such as stroke, heart failure, eclamptic seizures etc given 1-1 or even 1-4 support to help with their babies, even if this is a more junior "extra pair of hands" type role.
I would also like clear guidance on who should and shouldn't be on the ward, particularly when the women are physically unwell and not able to 'gatekeep' or 'host/entertain' people she doesn't know well, but are keen to get a look at her baby and threaten to take it away/refuse to hand the baby over and take up the whole of visiting time etc. It would be helpful if there was someone watching the area generally so that babies can't be removed from the ward by visitors when the patient/new mum is sleeping, as I found this terrifying to wake up to. I would have liked my own parents to have priority or at least equal access to the ward as my PILs (who I'd only met a handful of times before).
I had a reasonable experience with the Bounty rep but know this isn't the case for everyone, and think having them there contributes to this image of new mum as 'fair game' for people to take advantage of - so added to substandard medical care 'because you're a mum now', intrusive visitors who you have to placate and be nice to 'because they just want a photo with the baby' and you're exposed to high pressure sales techniques when you're unable to sit or stand, trying to look after a screamy non-sleeping hungry baby, and will agree to anything to get a moment's headspace or privacy.
It would also be really helpful for women who have had a high risk or traumatic birth to be able to have follow up appointments if and when they are considering another baby. I have not been able to get a straight answer on whether or not it is advisable for me to risk another pregnancy and time is now running out. Advice has ranged from 'you will almost certainly die' to 'there is no medical evidence for 4th degree tears happening more than once to the same woman'. I was particularly annoyed when I was told that most 4th degree tears can be predicted from anatomy prior to birth, and think this should be part of pre-birth checks (I know that's not the focus of this campaign but could save a lot of time/effort/resource down the line post-natally).
Use of more empathic language is something I'd like to see as well. I would be really encouraged if the culture could be changed in this respect. Use of the dreaded 'not coping' and 'failure to thrive' could be couched in much more supportive (and less triggering) ways. Language used in the HV mental health check should be looked at as well, if you're completely blindsided about everything that's just happened to you, you are going to think your reaction is normal and it's okay to be down about it, which can stop you from accessing help to process the situation.
When issues caused by pregnancy and birth don't 'magically go away' i.e. incontinence, SPD, PND/PTSD etc it would be great to receive additional specialist help beyond the one-year limit you can receive from the NHS, and better GP education to help with these - in fact a few commenters have alluded to a whole-system approach across acute and primary care, which would be excellent.
Lost notes was a huge issue on my ward after they were handed back to ward staff (we had the women held maternal record in Scotland, not sure if this is UK-wide now, or has changed since I gave birth) and led to delayed discharge of at least 3 women, and meant that there was no record of my traumatic birth, which has made it difficult to access the ongoing help I needed and continue to need because there was no evidence of what happened, therefore it didn't happen, therefore no treatment/help could/can be provided. Better records management should be included in any campaign.
Finally, in terms of BF, there is a significant number of women who are unable to BF or have issues BFing due to under-development or non-development of breast tissue during puberty, and I don't think there is enough awareness of this, which means there is little or no support for this cohort of new mums.
