I wouldn’t be giving her anything other than a bus pass.
she has toiletries available at home, as long as she has the basics, good shoes and a coat and isn’t wailing around in rags she shouldn’t be asking for money for clothes, if she wants extra, she can work for the money.
If she needs jeans i would but her some from the high street or the supermarket, if she wants expensive ones that’s her responsibility to fund.
At her age I was in sixth form and working three days a week after school and on weekends.
completely by choice because I wanted money for clothes and socialising, I went to the cinema every week and to gigs every week, I also went out drinking every Saturday night, if I wanted that kind of a social life I was raised to know it was my responsibility to fund myself.
my parents paid for basic clothes, basically necessities, as long as I had a coat, good shoes and a couple of pairs of jeans and some T-shirts I was ok, anything expensive or extra I wanted but didn’t need I bought myself.
travel, they would pay for travel to school or work, anything socially was my responsibility.
toiletries, the basics, generic shampoo shower gel sanpro, toothpaste, etc, they would even pay for makeup if I asked for it, just stuff from boots, nothing snazzy.
but if I wanted a £12 bottle of Frizz ease, purple shampoo or expensive make up that was mine to buy.
they bought me a phone and gave me £10 per month for credit, but if I wanted the latest model or a contract that was mine to pay for.
Basically if I needed stuff they would pay for it, but anything luxury I saw as my responsibility.
growing up we were taught to use our pocket money in the same way, so we learned well.
I was earning around £150 a week, it was more than enough to fund my lifestyle and save a bit for big things like festivals.
I am raising my DC the same way.
