It seems that everyone is basing their opinion on the child's ability to use the restroom alone. My 6 year old is more than capable of using the restroom alone. If she had to go then DH could certainly send her into the ladies room while he waited outside the door.
But what if it was the Dad who had to go???
For those of you who are so adamant that this man should not have taken his girls into the restroom, what would you do? Would you leave your young daughter standing outside alone while you used the restroom?
I think if the girl was truly 10, then I might consider leaving her alone for a few minutes, maybe, depending on her maturity level. What if she was 8 and appeared to be 10? People mistake my 11 year old niece for 13 or 14 all the time. DD 6 has a friend, also 6 years old, who could easily be mistaken for 9. I would not feel comfortable leaving an 8 year old girl standing outside a public restroom without an adult.
So if the dad needs to go, then his only options are to take the girls in with him or to use a companion restroom. It seems that no matter what he chooses people will condemn his choice. He can leave a little girl standing outside a public restroom alone, he can take a girl into the mens room and risk her seeing male anatomy or embarassing the men inside, or he can use a restroom intended for the handicapped or impaired and be a villain for it because he isn't impaired.
