Popular pet names Rover, Cheryl and Kate could be a thing of the past. Banks are now advising parents to think carefully before naming their child’s first pet. For security reasons, the chosen name should have at least eight characters, a capital letter and a digit. It should not be the same as the name of any previous pet, and must never be written down, especially on a collar as that is the first place anyone would look. Ideally, children should consider changing the name of their pet every 12 weeks.

Expectant mothers have also been advised to choose carefully where they give birth. Anywhere that has a place name is best avoided. These are listed on maps, which are freely available on the Internet.

It’s a good idea too, security experts have warned, for children not to get friendly with certain teachers. For instance, Miss Smith may be enriching your son’s education but he should try and see if he can’t make a favourite of Father O’Grinnighan-Scythe II, even though it may mean a lot of staying late.
