A four-month-old baby with a rare vision disorder is now seeing his mother for the very first time.
WATCH: Baby delighted to see parents with her new glasses
Leo's parents say he's normally a happy baby, but the smile they captured on camera the other day was unlike any other they've seen before.
Little Leopold's glasses were specifically made for him out of rubber, with no sharp edges.
He can now get a crystal-clear view of mom and dad, and hopefully he'll give more of these adorable smiles for many years to come.
