IT WAS full steam ahead for members of the Sunshine Coast Multiple Birth Association when twins, triplets and their siblings took a ride on miniature trains at Nambour's Model Railway Park yesterday.

Sixteen families from around the Coast enjoyed a day out with the group which provides a support network and regular events for families who have, or are expecting multiple births.

Member Bronwyn Jarrett said she had been in shock when she learned she was pregnant with twins.

"There was a lot of crying," she said.

"The thinking on the way back from the hospital was how many nappies am I going to need, I'm going to have to buy two of everything."

After the Pelican Waters woman gave birth to Alexis and Taylah, the logistical difficulties of going out with the girls made her feel isolated.

"Things like getting to the supermarket when you've got two babies, you've got to get the pram out," she said.

Luckily, a chance meeting with an MBA member at Kawana Shoppingworld when the girls were eight-months old put her in touch with other parents who understood her experiences.

With the twins now aged four-and-a-half, Mrs Jarrett said the whole family loved the group's social outings.
