DS 1 is 18 & has asked for an Xbox 1 for his birthday. It's a special birthday, so DH & I have agreed, (& we've got him one....ssshhhhh!) 
Anyway, DS 2 says he'd like a PS4 for his 14th birthday. His friend has just had one for his 14th & his other friend is having one for his.
We just don't have the money. Simple. Also, DS1 is having a special birthday 3 weeks before DS 2's. So, after lots of angst & tears, DS 2 asked if he could have money from us, money from Grandma and Grandad, money from Aunts & Uncles & use some of his bank book money.
I thought that this was a reasonable compromise, but DH disagrees & feels that DS2 argues & gets upset until he gets what he wants, (there is some truth in this). He feels that DS1 never asked for anything & that him getting an Xbox 1 should be big & special & not, "little brother has had similar too."
I feel like pig in the middle.
WWYD? I thought a gift of £100 for DS 2 + he uses all his other gifts from relatives + some savings would teach him the value of it.
Am I wrong on this one?
