Teen DS stealing from home

[Homemadearmy]

This has been an ongoing problem for years. It’s not all the time, but ds16 consistently steals stuf. He knows within reason I would give him money if he asked for it. Yet he took £10 from me yet again.
in the past he’s been grounded, had his phone removed, made to do extra chores to pay back the money.
we have had talks about it. He can’t say why he takes stuff. I keep saying if you ask I would have given it. But yet he takes, gets caught and lies.
has anyone managed to stop this behaviour

Personally I wouldn’t ever keep cash in the house going forward.

Hopefully he’s just taking it because it’s there and wouldn’t move on to stealing other things.

I used to help myself to cash at a similar age but fortunately grew out of that when I started working. I don’t think I liked asking for money because I was always asked what it was for.

What does he use the money for?
does he have an allowance and does he struggle to budget with it?

is he using it for junk food?
