This is in relationships as I am struggling with this conversation with my DH.
My DH has told my 6yo to go to the toilet on her own whilst out in public, once was a known venue where she has been many times, recently was a new venue but we were sat opposite the door in a restaurant, a toilet that she has never used before.
My view is that age is too young, heavy doors, locks and other adults not expecting a child to be stood the other side and opening a door onto her.
I wouldn’t want to see a bloodied nose or a hand hurt in a lock or hinge when it would have been just so easy to just have taken her to the toilet.
