Awesome Dad My Son Can Have Whatever He Wants ... Even A Doll

Mikki Willis doesn't care about raising his kids by "traditional rules" ... so when his son picked out a doll as his new toy, this awesome dad was all for it.

After 4-year-old Azai got two of the same toys for his birthday, Mikki brought him to the store to exchange it for a new gift ... and the first thing he wanted was a Little Mermaid Barbie doll.

Mikki says he's received tons of negative comments since posting the video ... but this amazing father isn't parenting for the negative commenters, saying -- "My job as daddy is to provide a safe playing field for my boys to play whatever game they choose."
