Ashton Kutcher has complained about the lack of baby change facilities in men's rest rooms.
The 37-year-old actor is a dad to five-month-old Wyatt - his child with fiancée Mila Kunis - and he is unhappy that he can never deal with dirty diapers in male toilets.
Ashton has called for a change and is offering a "shout out" on social media to the first public rest room that installs the facilities.
In a post on his Facebook page, Ashton said: "There are NEVER diaper changing stations in mens public restrooms. "The first public men's room that I go into that has one gets a free shout out on my FB page! #BeTheChange. (sic)"
Since welcoming Wyatt into the world, Ashton has been a very hands-on parent and he and Mila, 31, pride themselves on not hiring nannies to help them with their baby son.
He previously said: "We just want to know our kid. We want to be the people that know what to do when the baby's crying to make the baby not cry any more. We want to know, like when she makes a little face or something, we want to be emotionally in touch with her, and I think the only way to do that is by being the one who's there ... "Mila is the greatest mom. 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."
