A mum has come up with a cheap hack to make sure her children get enough sleep – while she won’t be disturbed early in the morning either.

When children aren’t yet able to tell the time, it can be difficult for them to know whether it is time to get up.

Which can mean them barging into your bedroom in the early hours of the morning demanding breakfast, TV time or just a bot of attention.

But Megan Gough came up with a genius way to teach her three-year-old daughter about the time and, specifically, when it is time to get more sleep and when it is OK to get up.

The cheap, simple and effective hack involves an inexpensive white IKEA clock, reports ChronicleLive .

Mum-of-three Megan bought a cheap white clock from Ikea and coloured in different sections, making it easier for her daughter to tell the time.

Before half six is the red zone, meaning it is not time to get up and they should go back to bed.

Between half six and 7am is the yellow zone, meaning it fine to get up and play quietly in their room.

And finally there is the green zone, from 7am onwards, when it is fine to wake up the adults.

Sharing a picture of her creation in a mum’s Facebook group, Megan, said: “If anyone’s going to be struggling with light mornings. This was a plain clock from Ikea, my 3 year old now knows when to get up. Green is good to go.”

Speaking to the MEN’s       , she added: “So she gets up when the glittery hand is in green, if she’s awake in yellow, she can play quietly in her room but not in my room and red is back to bed.

“She is really quite good, just the odd problem like waking me up at 1.30am because ‘I have no socks on’. Ha! But she does look for daylight to get up and I anticipate a problem with summer coming.”
