The smile says it all! Little boy with hearing loss hears Dad's voice for the first time!

Joyful tears ran down Mom's cheek when she saw her baby boy’s eyes open wide after hearing his Dad’s voice for the very first time!

Lachlan, who is now two years old, had been diagnosed with moderate to serve hearing loss.

At just seven weeks old, he received his first pair of hearing aids.

The smile says it all.
