I have 2 boys who are 10 and 12- they use the men's room together when we are out so no worries because they look out for one another. I'm really bothered by the insinuations that 10 year old boys are small adult devient men with nastie thoughts running through their minds all the time and that they stare at everyone in the bathroom-what do you look at when you are waiting to use the stall?
Up to when my boys were around 8 and 10 years old and they waited for me at the entrance to the ladies room, ( Atlanta here- don't turn your back or your kids will get hurt ) they never "peeked" into the stall- in my experience, only very small children do that kind of thing. I am the oldest of 18 kids and have taught in Ga public schools for years-I have lots of experience with 10 year old boys. They are sometimes gender curious but I'd bet my life on it that they would NOT be caught looking under the door in a ladies room with all the other adult ladies in attendance, I don't know of any that have girlfriends, and they, for the most part, just think girls are gross.
I hate it that 10 year olds are making some of you feel uncomfortable- they are just kids for pete's sake. Yes, you have every right to go in peace and comfort and I am truely sorry if there are any personally percieved problems but a kid's safety means so much more to me- please ask the parent to remove them if they bother you or better yet- it only takes a small bit of time to do what needs to be done- just wait a second or two till they are gone and think next time it might be your child that needs to wait with you if they are in a dangerous area known for predators like road rest areas, airports ect.... WDW didn't worry me because there were always so many people in the restrooms it would be hard for someone to molest your child with so many witnesses around.
When we traveled from Fla to New York without DH a few summers ago around that age frame, you bet my boys went into the ladies room and waited for me- they even used the 1st stall sometimes- no way am I going to worry that someone might be uncomfortable about them standing just inside of the door entrance while I take care of my business- I love my boys- they are growing up to be fine men -if they got embarrassed then too bad- they were around to tell me so- I've stood just outside the men's room and at times, I have talked to them the whole time that they were in there too when they had to go and their brother wasn't with us to escort them.
I worked in a grocery store as a young girl and a female adult was attacked and no one heard it or knew about it until it was over- it didn't take long- kids are not equipted to defend themselves against adult males who are determined to try something bad - if the op is uncomfortable then she needs to take them together to the family restrooms or just have them wait inside the door entrance - just my 2cents-
