‘I know that’s controversial’ Kristen Bell reveals the unusual bedtime method she uses to get her daughter to sleep

Kristen Bell has revealed the 'controversial' bedtime method she uses to get her daughter to sleep - but would you try it?

The Frozen star is often very candid about her parenting and regularly shares the challenges and dilemmas motherhood throws at her - like when she breastfed her husband, or caught threadworms from her daughter.

Her latest confession is a about how she gets her three-year-old Delta to sleep, a method she branded 'controversial'.

Speaking at the premiere of the film Pandas - for which she is the narrator - the 37-year-old revealed that she now locks her daughter is her room, in a bid to get her to sleep.

She told Parents magazine: 'Look, I'll get controversial. My 3-year-old [Delta] decided to stop sleeping about nine months ago.

'And every night, when we put her to bed, she turns the lights on, which annoys the 4-year-old [Lincoln], and she will move furniture, and she bangs on the door with different, hard toys.'

She then continued to say they lock the door on the outside so that she winds herself down.

'We switched the door knob. We turned the lock on the outside. I'm sorry, I know that's controversial, but we lock it when she gets in there, and we stand outside and say, "We love you, we will talk to you in the morning, but now, it's time for sleep."

'And after about 10 minutes, she'll wind herself down. And then, before we go to bed, obviously, we unlock it.'

The mum also revealed that her and her husband, Dax Shepard, take turns in working on projects so that their kids always have at least one parents around.

'It's a very particular family schedule when we're both working. Although I'm not working right now so he is taking on a larger workload', she told E! News.

'It's choreographed, I guess, to make sure someone is always there and present for our kids.'
