Variety, the children's charity, started KKS in a bid to help parents pay for back-to-school costs, such as uniforms, stationery and extra-curricular activities.
And it was in the sporting arena the grandchildren excelled but it would not have been possible without the help of Variety, Lynette explained.
"The sponsors are making those children be normal children," she said.
"They then don't have that thing where they can't afford it, that stigma attached to them. There's nothing worse than having to say, 'oh, my parents can't afford it'.
"We're not well off, we don't act like it and we do not pretend to be, but with the sponsorship, the kids get that little bit extra."

"We've had a lot of support from friends and we've lost a lot of friends from having the kids because socially we're not able to go anywhere," Lynette said.
"We're very distant from them and so that's really hard. But we've made new friends and they know where we stand and what's going on.
"Some of them don't have grandkids and they're our age, they just don't understand … they think we're crazy, sometimes we are crazy, but they're our grandkids."
Allan said he was nearing 65 years old and while he could have been retired by now, he and his wife of 40 years are still needing to work.
Self-employed, the Rowans run a commercial cleaning business but cannot operate full-time due to Lynette's health and because they have to care for the boys.
They had been caring for their grandchildren for the past 12 years after the then Child, Youth and Family knocked on their door.

"CYFs came to us and said if we don't take the kids, they'll be split them up and we'll send them around the country so what do you do?" Allan said.
"Even though I'm a lot older than their mother and father, they're better with us than with them.
"You do what's best for them, not necessarily the best for us but what's best for them."
The Rowans wanted to thank the life-changing help Variety and the KKS sponsors had provided their grandchildren.
