Tamas 🇪🇺🇦🇹🇭🇺 But the child does not have its own login to that account number and view and manage their own account and so learn how to deal with money and savings.
If I give one of my 23 accounts numbers and card, she would also need to login to my account to have an overview, but then can also access all my other 22 accounts, make payments and make changes to settings, codes, cards etc. That is not advisable I think.
Just make a €1/month children membership, with 1 card, 3 account options (checking, saving and a third for example). That way they can share their account with me, if parents and child might agree to have some oversight. Or not. And that way the child can manage it’s own account, payments, savings for whatever etc.
And that is arranged by many banks nowadays, for free...
