THEY say it's double the giggles and double the grins and double the trouble if you're blessed with twins.Now imagine having two sets of twins in just two years.Leesa and Tony Matkov had children Jye (now 11) and Cayla (now 9) when they decided to try for a third.When Leesa fell pregnant, she had a dream the night before the ultrasound that there would be four babies."I rang Tony and told him I was scared stiff," she laughed.To her relief only two heartbeats were revealed and a few months later Damon and Liam were born.The family were just settling in to their new home when they got a "pleasant surprise" - Leesa was pregnant again."I was sick from the start and the doctor reassured me that there was little chance of having twins again," she said."But then I went in for that ultrasound and saw the two little sacs.""Everyone else was more shocked than us, they all thought we were joking."Leesa recalled her dream from the previous year and said it seemed "written in the sand" that they were destined to have four baby boys - just not all at once.On March 13 this year Mitchell and Lachlan joined the brood, taking the total number of children to six.Both sets of Matkov twins are fraternal, were conceived naturally and carried to 38 weeks."We're very lucky, but it's going to be very noisy with five boys around the house," Leesa said.Not to be forgotten, nine-year-old Cayla said there were some benefits to being the only girl."They'll care for me because I'm the only girl and I won't have to share a room," she grinned.Mornings at the Matkov households are the most hectic time of day, with two children off to school, two toddlers running around and two newborns to take care of."It's highly demanding at the moment ... we're trying to get a routine going," Leesa explained.However, having two sets of twin boys does have it's perks.Clothes are easily passed down from one set to the next and all the necessary baby items are already double-stocked."It's the perfect set-up for a high volume, large family," Tony joked.
