Ashton Kutcher is a grumpy daddy! The on-the-go new father is unhappy that there are no diaper changing stations in men's bathrooms, and took to Facebook to air his grievances.

"There are NEVER diaper changing stations in mens public restrooms," Kutcher wrote to his 18.7 million Facebook followers. "The first public men's room that I go into that has one gets a free shout out on my FB page! #‎BeTheChange."

Kutcher and fiancee Mila Kunis had their daughter Wyatt Isabelle in October.

In December, the 37-year-old funny man gushed about his lady love when he stopped by The Ellen DeGeneres Show. "The most amazing thing about having a baby is my partner, Mila," he told DeGeneres. "She's the greatest mom, I can't even. I go to work every day and I come home and she's, like, perfect. And it just seems like everything went amazing. And I know that something probably didn't go amazing, but she never tells… it’s unbelievable. She’s incredible."

Aww we love them!
