I LOVE Jo Frost, aka Supernanny - really I do.

It's just that I don't believe for one minute that the little tearaways she so effectively tames using her revolutionary "naughty step" don't revert to their spawn-of-satan behaviour after she's gone.

The programme is compulsive viewing none-the-less, with the current series throwing up some especially tough challenges for our heroine.

Last night Jo-Jo was dispatched to North Wales where she attempted to re-programme the four children of desperate Lin and Ronny Wynne Jones.

With an age-range of two to 13 to contend with, she needed every technique she can muster to get rid of dummies, improve behaviour and stop that holy racket.

And it didn't help that the dad of the family seemed intent not to lift his finger to help.

But with her tough-talking, endearing mis-pronunciation ("This is not asseptable behaviour!") and patience, good old Supernanny did it again.

I just wonder how long the peace will last in the valleys.

And, incidentally, has anyone else noticed that Supernanny has ditched her trademark prim and proper uniform, glasses and bun and transformed into something of a sex siren?
