The Government should introduce stronger rules on junk food advertising to save parents from 'pester power', according to the British Heart Foundation.
A poll of 1,000 parents for the charity found 74 percent are frequently asked by their children to buy them unhealthy snacks.
Some 42 percent of parents said their children were triggered by junk food available at supermarket checkouts, while 26 percent said offers such as buy-one-get-one-free made their children pester them.
Almost four in 10 said their children were influenced by TV adverts for junk food, while 24 percent were affected by other advertising, such as banners in shop windows.
We chat to psychologist Emma Kenny (and her boys) about pester power and what we can do to control it!
