I don't have a biological urge to have a child, it's just never existed for me. So for us, it comes down to logic.
I'd have to put myself through pregnancy and birth in a system that is at best woefully underfunded and at worst completely ignores the voices of women when it comes to pain, dignity and repairing the damage that could be done to my body.
I'm lucky enough to have a DH who does more than his fair share but I'd have to lose a huge amount of sleep and devote more of my body to growing said child should I want to breastfeed. I have a disability that I receive no support for from the NHS and is made worse by lack of sleep, overstimulation and lack of routine.
I'm lucky that I'd get a well paid mat leave from my employer but then in order to return to work, over 80% of my income would go on childcare, more if we had more than once child. I'd also have to compromise my career by not being able to stay late, arrive early or travel as much as I currently do so my future earning potential would be capped (household or just mine, depending on how we split the load).
When the child is out of paid childcare, we will have to continue to fund wraparound care and compromise on our careers. The child would also likely inherit my disability which is not taken seriously by the education system or NHS so I'd face a battle to get them even diagnosed, another battle to get them the right support and even then factor in that home or private schooling might be necessary.
On top of that I'd have to steer my child through a world where they may never afford to buy a property without familial support, where usual run of the mill jobs don't afford a decent standard of living, where climate change may impact their future, war is becoming more frequent and navigate teenage years in the age of internet predators and explain complicated debates around sec and gender. It absolutely terrifies me.
Quite frankly, why on earth would I have a child, without that biological urge to?!
