This isn't helping! 
See, what he really wants is a games console or a computer.
I don't feel we can justify spending that kind of money on a toy. We don't have a lot of money and there's no way we're spending anything like £200 on his sister's present.
But then I reasoned, if it was a computer, then it'd at least be educational. I could justify spending all that money on something if it was investing in his education / skills. And he is showing interest in coding. And he'll be going to secondary soon.
But then, looking at computers, although we can get a computer for about £200, the ones you use for gaming are much more than that aren't they?
So if we pushed the boat out and spent £200 on a computer, would it actually be a disappointment?!
EVERYTHING he wants is tech related. (What he wants most of all is a VR set, but he's not getting one of those as I don't like the idea of him being on it all the time, which he will be!)
