Some people swear by raspberry leaf tea, some by a hot curry and others by sex.
But for one mum, it was comedian Michael McIntyre who had the magic touch.
Heavily pregnant Cara Brown was in stitches when she went to see the funny man perform at London's O2 arena last Thursday (1st October).
So much so, within two hours her waters had broken – six weeks early!
The 28-year-old from Essex was rushed to hospital where she gave birth to her fourth daughter, weighing 5lb 1oz.
Cara told The Sun: "It was chaos because we didn't have my hospital bag, notes or anything with us. Any other pregnant women going to his gigs need to go prepared."
Among the well-wishers racing to congratulate her, was the man who made it all happen. Michael McIntyre commented: "I've sent Cara flowers – and a DVD in case her baby wants another brother or sister one day."
