We have two DSs aged 12 and 9. We live overseas, so Christmas and birthday presents from relatives are increasingly money / vouchers. Because DS1 has his birthday a couple of days after Christmas, he's received over 250 euros from various relatives and friends!!
He is dead set on spending lots of it - mostly on plastic tat that we generally refuse to buy him. Bobble head Star Wars figurines, Harry Potter stuff etc. Also games / v-bucks and sweets, etc. He is very opposed to us putting any of it away as "savings" as he thinks (correctly) that he won't just have free access to it after that.
He doesn't have his own bank account, but we are going to open one asap (12 is the youngest age to have one where we live). It will have mobile banking so he can always see his balance and - importantly - where it's being spent.
Are we BU in not just letting him blow 250 euros on plastic crap and sweets? I know IABU referring to the things that he chooses to buy like that and unfair to him, so I am really trying to button my lip in that respect. His stance is that people have given him money to be spent on presents (his cards from grandparents generally do say "spend this on something you like") and it's not meant to be saved. DH and I feel it's a great time for him to start off with a pot of money, that we can add to with pocket money over time, and he can learn to spend / save sensibly.
AWBU? How do you manage (or not) what your children spend gift money on?
YABU = you don't get to decide what a 12 year old does with money that has been given to him by family and friends, let him spend it as he likes
YANBU = you do get to say No to spending 250 euros on plastic tat, and insisting that at least some of it is put away as savings
