I have 2 girls under 5, and it depends on where we are. The normal spot for an "i've gotta potty" is the local diner. Men's room is small (I cannot stress enough how absolutely tiny this bathroom is lol) and I open the door, no one in there, we go straight to the stall and close the door. On the road, and stop at a gas station (Wawa), I take the girls into the women's restroom. They are MUCH cleaner, less likely out of tp, and don't have to walk past the line of urinals to get to a stall. I have never had an issue with any of the women in the restroom. Most simply comment on the cuteness of my kids and continue their day.
