FWIW the first post to mention disabled toilets was MissMuseli who holds the early title of being only the fourth contributor to the thread. Fanjo's post was written at least 20 minutes later.
By that time, 9 other posters had written that they preferred to use a disabled toilet in order to be able to take their pram into the cubicle.
Only 3 of those 10 in total mentioned whether or not if the toilet being either disabled or family friendly would influence their decision, and we all know how it spiralled from there...
This was my first post:
*Seconding the posts of MrsDeVere and Dawndonnaagain.
Please do not use the disabled toilets unless you are disabled.
Of course if you are doubly incontinent after giving birth you are entitled to use the disabled loos, not every disabled person is handed a blue badge upon diagnosis/accident/injury, nor is every disability permanent.
It's not okay just because there is no one waiting when you leave the disabled cubicle, either.*
Personally I think it's plenty polite enough. I think each one of us (posters who are carers & disabled posters) was polite at the beginning. There was significantly less awareness, understanding or respect from the mothers of children whose prams they wanted to be in the cubicle with them.
