I like taking my four-year-old daughter for movies without her mother, but have a problem with her using the men’s restroom. What do I do?

You can let your daugther to use handicapped toilet and all shopping malls have this facility. A 4 years old kid should be able to use the toilet seating (just make sure you wipe the seat cover before hand using sanitiser). You can wait for your daugther outside of handicapped toilet.
