With working tax credits, child tax credits, child benefit, minimum wage part time job, and child maintenence, me, ds (7), and two pets have £38 a day between us. It's tight sometimes but I try to make and stick to a budget, so we manage, always have the basics, food, gas, electric, wifi, netflix, now tv (reduced price atm then it might have to go too), toilet roll, cleaning stuff, shower gel etc and enough for the odd treat, lunch out with family now and again etc. Always managed to get a gift and card for the birthday boy/girl when ds has been invited to a party, even if it was just a cheapy one, colouring book in a cute bag or whatever. I'd say I'm relatively skint, rarely go out to socialise (will invite friends over or out for a walk or whatever instead).
I wouldn't say we were living in poverty though, we have far too many creature comforts to qualify imo. Since I lost my overtime (covering another staff member), I've had to cut way back in the last few months, on takeaways, going to the bakery, I quit cigs (but not smoking sadly, now I smoke the cheapest legal tobacco I can find, which costs me about £6 a week), buying drinks when out and about, using the gas wisely and not willy nilly etc, and have managed to save enough for a decent christmas, and weekly driving lessons (of which my dad pays half, he insisted which was unexpected, but which I'm so grateful for). Hoping if I can keep this up, I'll actually be able to afford to run a car if I pass my test. I'm in some debt, have an overdraft with my bank that I'm well into, but I pay the monthly fee, and reduce it when I can. Ran it up when my ex was living here, trying to keep up with the Jones's, so to speak, stupid I know. That's the height of it thankfully, no credit card debt or anything like that. I'd say we do okay, if I had more than the one dc I think I'd really struggle though.
