At 7 weeks old, baby Lachlan had never heard the sound of his parents' voices before. But thanks to his new hearing aids, we get to see this moment of shock that quickly turned to delight. And that's just mom and dad's reaction. The baby was pretty happy, too.
Proud dad Toby Lever, who posted the video on YouTube, explains that Lachlan had been diagnosed with moderate to severe hearing loss in both ears. He's now two years old and doing "remarkably well."
