How can I change my daughter's diaper in public, she's disabled?

let me start with Im so sorry. Life sometimes isn't fair. But to answer your question. I have an 11 year old grand-daughter who was born with spinal bifita. And she has zero feeling of her lower body and no control over her bladder and bowels. So her mom takes a light weight rolled mattress pad where ever they go. Using a public bathroom can be challenging, especailly if it has more than one toilet. So ask a worker to please, make sure no one enters into the bath room while you are cleaning up your daughter.
