Usually you can find family changing rooms. If not, you ask a member of the team to go to the changing room, ask if there are any women, if not let the dad go in and wait by the door. If a woman comes the team member would let her know that there's a man inside and she'd choose if she's going in or not.
Hang on - So men should have a right to go into women's changing rooms and women are the ones who have to make the decision wether or not to go in with a man there? And presumably lump it if they don't like it? And a staff member on hand to manage this? Whaaaat! You can't be serious?
So can women take little boys into the men's?
But let's flip it here. Most facilities like this have posters that say "cleaned by members of both sexes". If a team member came in for a problem (somebody asked for help for example) what would you do?or you would expect the person in need to wait for a female member to come in?
Facilitates need to be cleaned. If someone has been hurt, a staff member needs to come in. Dads with little girls do not need to be there - there is a perfectly acceptable facility in the gents to take their child into
When your dc were babies, if the gents didn't have a changing table, what would you expect you ex to do?
Find a toilet that did. Or use the baby mat on the floor. He certainly wouldn't go into the ladies!
Are you going to answer my questions about why girls can't go into men's toilets/changing rooms with their dads, and what a man should do if he has children of both sexes with him?
