I have a disabled relative too, in particular a teenage niece who is a wheelchair user and severe learning disabilities and so needs assistance to use the toilet and, on occasion, be changed if she has soiled herself.
When I soil myself I also need assistance to be changed because of my disabilities. It's hugely humiliating and I don't always have someone to support me when this happens. It shouldn't happen because there should be adequate facilities for me to use before it gets past the point of urgency. When the facilities are left for the right people it's more likely that those who need it will get to use them in a timely manner and mitigate accidents.
I don’t take her out so much now but pre children I did frequently.
Its hard to tell from your post if she no longer gets out at all as frequently or if someone else has taken over and she still gets out but if she can't get out more frequently then surely you can understand how isolating having a disability can be, especially if you have had multiple instances of soiling and no immediate support because of barriers to accessing disability accessible facilities.
My views are not formed from a lack of experience of disability and the challenges being disabled poses.
Its a tale. How can you have those experiences and still think that you and your 2 non-disabled children could trump the needs of your neice or those like her? If they were all in a line outside the facilities who would you let in first?
Again, it’s a balance of needs.
Right. I get it. Some cubicles are small. Some. But you have the privilege of being able to go and locate facilities that can accomodate you and your 2 children. If your kids are young you can use a travel potty if they have urgency issues. You can stand outside a cubicle while they both go in together. Many facilities have a larger cubicle within their main toilet facilities separate from the accessible disabled toilets. If one establishment doesn't have this there will be one nearby that does in most places unless you live in the outer hebrides. Whatever the area there will be a solution that means you can toilet your children safely.
You are mixing your convenience with our necessity. It's convenient because you're guaranteed to keep your children in one space in these toilets, but it's necessary for those services to be there because us disabled can't access the other facilities available with ease or at all.
