What an incredible moment!

This absolutely precious baby boy is named Lachlan. At just 7-weeks-old, he had his hearing aid was turned on for the first time.

The look of wonder on his face is truly amazing!

His parents said, "Our beautiful son Lachlan was diagnosed as having moderate to severe hearing loss in both ears. When he was 7 weeks old he received his first hearing aids. His reaction when they were turned on was truly amazing. We cried from happiness."
