What is the appropriate thing to do?

He should take her into the men's room himself and go into a stall (a handicapped one preferably, if available) and then let her use it. She'll be fine, she won't see anything if she's not looking for it.

The best thing for him to do is take her to the men's room if she's not old enough to go alone. If he fears she will see too much, he can always stand outside the women's bathroom and wait for her to finish or quickly take her to a stall in the male's bathroom. Hope this helps.

My husband takes our daughter into the men's room. It is never appropriate for a man to go into the women's room, as it is not appropriate for the woman to go into the men's room.

He should take her in the mens room in the stall men do it all the time no reason to feel embarrased.

He should take her in the mens room. Being that young, she's really not gonna care what's in there - just that she makes it to the potty in time :)

he goes in the mens room ..makes it clear to everyone he is bringing his daughter in ..and he guards the door to warn new people coming in ..honestly I would never let my child use a public restroom ..they are disease centers. Hit the bushes
