I think your daughter will be fine OP.
Mine is still in uni and gets the maximum loan/grant and I can’t afford to give her regular monies, but she had a couple of thousand of Child Trust Fund behind her, and she has not needed to dip into it.
I pay all her travel to and from uni every term and half term. I still pay for her mobile phone, which is cheap as it is long paid off. I bought her everything she needed to set up in halls, eg linens, mesh laundry bags, a rack that sits over her radiator for clothes that don’t go in the dryer, and I spent about £150 on her first food shop which mainly included dried goods like pasta, spices & herbs, sauces etc and which she used to cook from scratch all that first term. I also left her a couple of bottles of wine. Her uni is quite far away and I only get to visit annually but I still leave a “shop” behind. Her halls were about 2 miles from uni snd she always walked in and out. I buy her clothes and trainers for Christmas and birthdays or give her money and a small token gift or two. She also had to pay a halls deposit of about £500 before A level results even came out, and I lent her that - but I waived the loan as the main part of her next birthday present. So that saved her lots that first year.
DD was very surprised how few of her peers knew how to cook. She teamed up with a friend and they did dinner together every night. They made curries, pasta bakes, and similar, mainly vegetarian as cheaper. A meal lasts them about 3 days. DD is queen of yellow sticker shopping and enjoys the challenge of eating well for less. She sends me photos of her successful hauls!
They almost never go out clubbing or to pubs but they drink wine with friends, initially in halls and now in their student flats/parties. Their student halls flat had regular games nights. She uses my Netflix subscription and her flatmate uses her parents’ Amazon account. They don’t watch live TV or iplayer so they don’t need a TV licence.
She gets almost all her uni books from the library.
I bought DD a small coffee machine and milk frother for her birthday once she moved into her first private flat and the girls buy fancy pods rather than costly coffees en route to uni.
DD only worked during the holidays for her first year in order to settle in. Then she got a job in a shop to get the employee clothing discount- and she is still there. She loves that job and really likes her Co-workers. Unfortunately her shop job doesn’t have a branch near where I live but somewhere like Tesco or M&S is a handy one for shifting between term time and holidays. DD’s term time is 22 weeks + exams so plenty of time for her to work outside of this.
I think DD still feels poor, as her uni seems to have a lot of wealthy privately schooled kids, but she has everything she needs, independence, does some volunteer work, and is healthy and happy. Having access to discounted trendy clothes from her job helps her feel like she’s keeping up with those well-dressed, confident-seeming rich kids at university. I hope & expect your DD thrives. Giving your children a secure loving foundation is the best preparation for life and I’m sure you’ve done a great job.
