Parents spend loads of money on present for their kids in christmas,is it fair for santa to take all da credit

it's fun and when they grow up and learn the truth they'll appreciate everything their parents did for them anyway.
its just to make the kids happy and excited. remember when you were little and you found out that "santa" came? Those presents were always so exciting. THe kids will soon enough realize that santa is not real and thus understand that all those years it was their parents and they will not only appreciate all the money on the gifts spent, but also that their parents let them have a magical and special holiday where they could believe in santa claus.
