The Location Location Location presenter, who has two sons Bay, three, and Oscar, one, said: "I resent women in the public eye who look glam, do glamorous jobs and try to pretend they have it all when they don't. You can't have it all without help."
She said: "It puts pressure on all mums. Even as a 'celebrity mum' myself there is now a huge expectation that you'll have a natural birth, get your figure back immediately, take naturally to motherhood and continue a successful career. It's rubbish."
As well as her sons with property developer Ben Andersen, Kirstie has two stepsons, Orion, nine and Hal, six, Ben's children from a previous marriage. And she is happy to admit she has a housekeeper and a nanny to help.
Kirstie admits she wishes she hadn't gone back to work just three months after having Oscar in August last year. She said: "It was too soon. He was born when the recession was starting to bite. People were saying property shows were finished. I panicked as I thought I might be out of a job. That's one of my big regrets."
