You've heard of Super Nanny, now meet Nappy Nanny. Tracey McDonald is on a mission to cut landfill waste with the help of a secret weapon -- reusable nappies!

Tracey and husband, Martin, of Woodplumpton Lane, Fulwood, are two of a handful of new 'Nappy Nannies' drafted in by the county council, as part of the Bottom Line Real Nappy Project, to pass on their experience of raising children without using disposables.

The couple, who both work at the Royal Preston Hospital, say they have never used throw-away nappies on their children, Daisy, four, and Tom, 20 months.

Both parents are passionate about caring for the environment and are keen on 'doing their bit' to help save the planet.

Tracey, a physiotherapist, said: "One of the reasons we went with the real nappies was because of a quirky saying we kept coming across, 'You don't inherit the earth from your parents, you just borrow it from your children'.

"They appeal to us for the green side and it's a bonus because it works out such a cheap alternative.

"It's estimated that a parent would spend £960 on disposables per child, from birth to potty, whereas I've spent £200 on nappies for two children."

To help spread the word, Tracey and Martin, a nurse practitioner, visit families, prospective parents and health professionals to explain the options available. "The days of soaking, pins and plastic pants are long gone," said Tracey. "Modern nappies are really trendy, come in all shapes and designs, and use Velcro and poppers so there are no big safety pins. We both work and have never found it a hassle to wash them, usually one load a week."
