Little Lachlan's parents uploaded this video of the infant at the doctor's office as the hearing aid is being placed in his ear. Watch as he first cries (we're sure that was a little awkward and possibly painful) and then realizes that he can hear the world going on around him.
"His reaction when they were turned on was truly amazing," Toby Lever writes on YouTube of the hearing aids. "We cried from happiness."
Even better news?
His parents say Lachlan is now 2 years old and doing well.
