I think my main issue is that the idea that mothers should just get on with it without moaning and just grin and bare it, is inherently rooted in misogyny.
Think of a C-section. There is no other major operation where you would be discharged 24 hours later and sent home sleep deprived to provide 24/7 care for a newborn baby. You can expect more support for a broken leg. I had a section 3 months ago and haemorrhaged. I was very weak and unwell after birth, whilst desperately trying to establish breastfeeding. I passed out twice and could not keep my eyes open mid conversation, but staff still wanted to discharge me the following day, when I was in no state to care for a newborn at home. I couldn't even hold her safely as I was constantly falling asleep! I imagine it's the same for women who have had traumatic births, or women who have laboured 3 days.
Women go through major surgery or birth and are given no time to heal and get a full night's sleep in hospital, which in my opinion would go a long way towards helping new mothers cope. Women are so vulnerable post-partum due to the shock to your body, and the change to your hormones. A prolonged period of hospital or community support to help with baby would go a long way in helping.
It's not about families individually so much as how society treats women who have gone through a significant medical event. If men could give birth, I guarantee you things would look different in terms of support and discharge home.
On an individual level, we'd all visit someone elderly with reduced mobility and offer to do some pots and make a drink, but apparently it's unreasonable for mothers who may have experienced tears or surgical intervention to expect the same? Please. It's just basic human decency. But women's pain and health conditions unique to women are not taken seriously.
