This photo shows how diaper-changing stations in men's restrooms are still too rare

(CNN)Donte Palmer isn't the only dad who's had to squat on a dirty restroom floor to change his baby's diaper.

He's just the newest face of a movement that's been going on for quite a while: to install baby-changing stations in men's bathrooms.
The 31-year-old high school teacher was at a steakhouse in Jacksonville, Florida, with his wife and three sons, when 1-year-old Liam started to cry. Palmer knew the boy needed a diaper change.
So he did what had to be done: He picked up his baby, recruited his eldest -- 12-year-old Isaiah -- and headed for the men's room.
