"For a lot of children Santa can be quite a scary figure. That idea that he is watching all of the time can be quite a frightening concept," says Rachel Andrew, a clinical psychologist specialising in child and family psychology. Andrew believes using Santa"s "naughty list" as a behaviour management tool is flawed in numerous ways. "Having children believe they are on an imaginary naughty list for behaviour they have done over, what, an entire year? Three or four months? It"s so far against what we know is likely to encourage positive behaviour in our children," Andrew says.
