Meet Mr And Mrs Bates - And Their 18 Children

These days, the thought of having three or more children sounds like a lot to most of us. But not for Gil and Kelly Bates, who are celebrating having their EIGHTEENTH child – and they say they hope to have 'many more'.

The couple, from Tennessee, US, married 23 years ago, and housewife Kelly, 43, had a baby in almost every one of the first 15 years.

The Bates look set to become the biggest family in the world one day: they are only one baby behind the Duggars family of Arkansas, who have 19 children and are currently believed to hold the record.
