Just curious really,my niece who is 5(She has been sworn to secrecy) knows the secret of Santa but my daughter who is 6 still believes and obv want to keep it that way aslong as possible but I am very aware that maybe next yr she will find out from school etc. What age did your kids find out,did you tell them or did they find out from another source. I was about 8 I think when I found out from a friend at primary school whos brother had told her all about it! I do however still believe!!
