Can anyone recommend an Alarm Clock for a 4 year old girl please?

[peachcake]

I would like to get an alarm clock/sleep aid for my daughter so that she gets up for school in the mornings (she is never out of bed on time) And one that would keep her in bed on weekend mornings when she is over enthusiastic to get out of bed too early!

Does anyone have such a thing?

Many thanks :-)

We have a gro-clock for DS, 3.5, which he likes and it comes with a story book that explains about the importance of sleeping when it's sleepytime and staying asleep till waking-up-time.

We've got an OKtowake clock which works well.
