DS1 and 2 are 11 and 9, I think that DS2 is a FC believer but I'm not sure about DS1.
I don't want to out right ask and have him question why I'm asking and I don't know if I should tell him the truth, he's the type that would let slip to his siblings when he's in a bad mood 
He's still at primary school (yr 6) and I have no clue if he just goes along with it I. Hope
Of getting more pressies or if he genuinely believes?!
Any advice?
