ILLARIA Badolato refers to it as her "bad ear" — the three-and-a-half year old's right ear that didn't form at birth.
Her microtia means she will be permanently deaf in one ear for the rest of her life.
So what is the Hoxton Park resident going to do with her "good ear"? Get loud of course.
You see the Hoxton Park resident is not alone. One in every 1000 Australian babies are born deaf and three in every 1000 children being diagnosed with significant hearing loss by the time they reach high school.
This week Illaria's childcare centre Kindikids will celebrate Loud Shirt Day in all three of their Fairfield centres to raise funds for the The Shepherd Centre, one of Australia's leading providers of speech and language services for children with hearing loss,
More importantly the loud and bright outfits are designed to raise awareness about the importance of hearing loss in children.
Illaria's mum Monique knows just how important that is.
"It has been a long road for us with lots of appointments and tests and it wasn't until last year that Illaria was diagnosed with microtia," she said.
"I guess we were one of the lucky families because she still has hearing in one ear and with her new hearing aid we have seen a big improvement and she now responds first go and can comprehend where the sounds are coming from."
