They find a way because they have to.
Often involving a precarious system of loans, credit cards, overdraft, borrowing from family and friends, sometimes getting stuck in the payday loan cycle. Using food banks, doing illegal stuff to make a bit extra like drug dealing (even minor stuff like selling your painkiller prescription you no longer need to someone), sex work, cash in hand work. Working multiple jobs at once.
Yes, it’s shit. I don’t have kids yet because until the past few years I just haven’t been in a stable enough financial position (I’m 30 and it’s taken several years at uni, working multiple jobs at once, to get to where I’m at now where I’m on a similar wage to you with a partner on a slightly better wage).
I’m tentatively planning on trying for my first child next year, have a savings account I’ve been working on for the past year and a projected idea of what I want to have behind me before TTC.
I’ve been absolutely bones of my arse so skint where I couldn’t even afford a prescription to treat a chest infection but couldn’t miss work because I wouldn’t be paid enough to keep things afloat so had to spend a week at work increasingly ill (I’m asthmatic) before I got paid to then skip meals to afford my antibiotics... and considered some seriously risky actions to try and keep afloat. I would never bring a child into a financially insecure environment (I can only speak for myself and no judgment on other people’s decisions there), even though I know you can’t plan for everything we’re doing a pretty good job to try our best.
