Let's Talk Bathrooms!!

Well the bathroom talk has been a hot topic! So I'm jumping on board!! So my daughter is in a wheelchair and I have had to take her into the men's washroom with me and ... Well since we cannot use a regular stall or toilet, I drag a specialized commode and set it up, I then transfer her ( lift) onto it and then step out for a minute so she can have a little privacy. So what are the proper steps for this situation. Should I allow her to be exposed to the male etiquette or walk into a ladies restroom and set up and make the ladies aware that I'm her father and caregiver? What about parents that need to use a stall and Change there family members on the bathroom floor? This is probably the hardest thing in life and the biggest part of our outings or traveling that stresses us out the most! I'm sure I'm not alone on this. So imagine a long trip somewhere and planning rest stops....We make a lot of backroad pit stops! We need proper bathrooms , equipped for all and lots of them. It doesn't have to specify a ability, sex, color or religion... It just has to say " Restroom". No confusions there!!
