WATCH: Dad's heartwarming response to son choosing an Ariel doll

YouTuber Mikki Willis had a powerful question to ask dads everywhere after a recent trip to the toy store with his son Azai.

Azai had been given the same present twice for a recent birthday and they travelled to the local toy shop to exchange one of them for a new present.

While there, Azai wanted to buy a doll of Ariel the mermaid.
