IT'S DOUBLE, double trouble for one Bournemouth family who have conceived twins for a second time.

Natalie and Nicholas Joyner of Twyford Close, Throop, are the fourth couple in Bournemouth to have conceived two sets of twins in 20 years - and according to TAMBA (Twins and Multiple Births Association) the chances of doing so are just one in 3,000.

And the Joyners' children were conceived without any fertility or IVF treatment.

The family, who already have five-year-old twins Benjamin and Bethany and a two-year-old daughter, Megan, are preparing for the new arrivals and have just invested in a people carrier.

Natalie, 27, said: "We only found out it was twins at the 20-week scan and I cried - I'm looking forward to their arrival, but it's a bit daunting.

"Having had twins already, I know what to expect - we already have two of everything, including two car seats and two highchairs.

"I have written to Pampers and Huggies and asked if they'd like to sponsor us but as yet had no success."

Having worked as a children's nurse on the special care unit in Poole, Natalie is used to giving new parents advice on coping with twins.

She said: "I always tell mothers of twins to get an electric rocking chair so that when both babies are crying you can put one in the chair and concentrate on the other.

"I feel sorry for Megan because the idea was to have a fourth child so she wouldn't be on her own - now she will be even more on her own.

"I'm dreading the day I have five teenagers all in the house at the same time but at least they'll never be bored and they'll always have someone to do things with."

Natalie realised how rare it was to have two sets of twins after she received a letter from Anna Ward of Bournemouth Twins Club.

The due date for the babies is April Fool's Day but Natalie says she'll be prepared for their arrival at the beginning of March.

And as for whether the family plan to have any more children, Natalie said: "I don't know whether I can risk it but never say never - in five years time I might get broody again."
