DS is 12.
DS has a pocket money card, which never has more than £30 on it.
He also has about £100 of birthday money in a piggy bank.
I can't decide if
A, He should have all his money in a bank account.
Or
B, Have a bank account for his savings and his pocket money card for day to day spending.
I'm a bit wary of the birthday money getting frittered away. But I don't want to put it in the savings account that I have for him.
