Just occurred to me that you there seems to be a general trend on MN that as soon as DC hits secondary school parents have a chat putting to bed the whole father christmas idea. With those DC who still believe/play along with it past the age of about 11/12 must be on Asd/SEN or something similar (I forgot all the acronyms).
I have 3 DC, eldest 2 are just 12 & nearly 11 who either still believe or just play along with it whilst youngest is 6 and very much still fully signed up. I know they will get to an age when too old etc but with younger siblings, I'm happy to play along with it for a while yet.
I don't remember having a chat with my parents or officially being told about it.
Am I being a nieve parent or just someone who likes seeing this part of Christmas?
