Definitely teach some some key life skills. Start with how to make a cup of tea (using teabag in a mug) and a cup of coffee (instant is fine).
Teach her how to use a washing machine but if she is going to be in halls, she might need to learn how to use an industrial one, so take her to a laundrette too. She also needs to know how to sort her own laundry into darks, lights, delicates, and not to overload the machine, nor, as a friend of mine reported - use a full wash cycle for a single pai of knickers!
How to make her bed.
3 basic meals she actually likes that have some nutritional value. Even if it it just filled pasta with pesto, beans on toast and cheese omlette.
Washing up, too. Make sure she scrubs things clean, rinses them properlyt and dries them off.
Get her to practise these things by cooking for the family, making cups of tea for everyone, helping with dishes, doig her own laundry sometimes.
