9 year old stealing money

[Silab]

my 9 year old son stole about £4 from his dads wallet about a month ago. grounded him for a fortnight and banned him from all electronic devices for a week (x-box, t.v. etc). tried to make him understand how unacceptable this was.

tonight he has taken £10 from the sideboard and £5 from his dads wallet. i don't really know the best way to deal with it. he is very impulsive and doesn't think of the consequences of his actions. he wants a remote control car and this was his way of getting the money for it.

any suggestion for how to deal with this would be appreciated. i am worried where we'll end up if i get this wrong.

No idea but bumping as sds is the same, been going on for a few years and now have to lock money away :(

Why does he need the money? I'd just tell him you know he's taken it and you want it back NOW.
It's a nuisance, but don't leave money lying around that's obviously a temptation he can't ignore.
Does he get pocket money? Try and talk to him to find a solution to it rather than having to punish him.
There are no definitive answers, but some helpful ones maybe found here.

DD nicks small change to go buy sweets (she gets plenty pocket money, too, just spends it elsewhere on different bits of tat). Maddening, no solutions, just sympathy. I'm more annoyed that DD keeps spoiling her tea than anything else.
