Parents often ask whether their child is too young, or too old, for a call from Santa. The short answer is that it works from about two until they stop believing, and often for a year or two after that. What changes is how you set it up.
Under three
They may not follow every word, but they know their own name and they know that voice. Keep it short and put it on speaker while they sit on your knee. The message for this age is gentle and mostly about Rudolph. The email version is a good choice here, because you can play it again as many times as they ask. They will ask.
Three to five
This is the heart of it. A child this age believes completely and will answer Santa’s questions out loud, even though he cannot hear them. Book the phone call, let them answer it, and film it.
Six to eight
They are listening closely now. The details matter: the right name, said the right way, and praise for something true. Choose the thing they have really worked on this year.
Nine to twelve
Some still believe, some are not sure, and some are playing along for the little ones. Santa’s message for this age asks them to set an example for the younger kids, which gives a doubtful ten-year-old a role in the magic instead of a reason to spoil it.
Grown-ups
There is a version for adults as well. It is cheekier. It works well on a flatmate, a workmate or a dad.
One call each
In a family with more than one child, each message says one name, so book one for each. Space them a few minutes apart, so everybody gets their own turn to answer.
