Bunbury mother of four Jess Turner understands how important the Ronald McDonald House is to families who need it.
Ms Turner's eight-year-old daughter Eden and her twin Willow was born at 23 weeks and as a result Eden's airways had suffered scarring.
At seven months old, Eden needed a tracheotomy to allow air into her lungs.
Now, Eden needs surgery every few months so she can talk.
All of this medical treatment has been done in Perth, with each visit the family stays at Ronald McDonald House.
Ms Turner said keeping the family together helped Eden as loved her sisters staying close to her.
"She finds the surgery less stressful to have everyone there," Ms Turner said.
The Turner family is just one example of why raising money for Ronald McDonald House Charities was so important.
McHappy Day is on November 14, but fundraising starts much sooner with people being able to purchase 'silly socks' or a 'helping hand' from October 21.
Bunbury McDonalds licensee David Eagles said there were plenty of ways to help out the charity which helps so many.
"We're calling on locals to dig deep and get behind this importance cause, which assists thousands of people each year," he said.
"In WA alone, annually Ronald McDonald House Charities helps over 1,929 families."
"Everyone at Treedale, Bunbury South, Dalyellup, Macca's is extremely proud to host McHappy Day each year.
"The funds raised through this initiative are crucial in helping Ronald McDonald's House Charities continue to keep families together while their seriously ill or injured child undergoes treatment."
