His birthday is December too.
He likes gaming so for his birthday have got him a gaming chair, headphones, 2 games he wants (gonna look crap wrapped up but they were 50 quid each
) and some small bits.
Now for Christmas he won't tell me a thing.
He says he doesn't want anything as he has everything he needs
Which is lovely and sweet and unexpected from a teenager but also incredibly frustrating as a present buyer.
He used to read but he just cares about gaming now 
He isn't into clothes.
Not into music
He says he doesn't want money as that's sad at Christmas.
I'm pulling my hair out.
I need suggestions please
