Is it? oh good! he did say before term eneded that a boy in his class (yr 2) didn't believe so I sort of thought he knows anyway - this boy has older brothers so they had obviously all been discussing it at school
You might find that he goes along with the whole FC thing next year. I sort of pretended to believe for ages after I learned the truth - it's just as magic if you pretend. I mean, I put the presents under the tree these days but still get foolishly excited.
I say if you believe he's real then he's real and Obviously, FC only comes if you believe. Even if it doesn't convince him, it should lead him to pretend he believes, so your DD can keep the magic a bit longer
DS1 thought it was all rubbish 2 years ago, but this year he is an absolute believer (so he tells me )
my 7 year old had doubts but then with the leaving the drink and snack out, the norad santa tracker and the fact that Santa replied to his note he totally believed on Christmas Day. 6 is far too young not to believe in my house,my 11 year old is no longer convinced but I keep telling her of course he is real !
