For those of you on means-tested benefits or low incomes and with no/little savings, there are charitable grants that you can apply for if your oven/washing machine/etc breaks and you need a new one. You can usually apply via your local Citizens Advice.
Also, bit of a derail, but... Some people do think poor people shouldn’t have children, I think that’s a pretty disgusting attitude.
However I do think everyone should think carefully about the number of children they have, not only on an individual level (can I provide for these children practically and emotionally) but also on a population level.
I also think it is a strange choice to spend a lot of money on pets if you have a low income and significant debts (especially rent arrears). I get that people are very attached to their pets, and pets bring a lot of joy, but rent arrears can make you homeless. I do like my cats but I would obviously choose my home over my cats!
