TUCSON, Ariz. — For many families, having a clean, discreet place to change a child’s diaper is what makes it possible for them to be out in the community.

For those raising children challenged by disabilities, that need might not end when the child is too big to fit on a conventional changing table.

That’s why Tucson moms like Marianne Scott and Amy Weaton want to see Arizona pass a law this legislative session requiring newly constructed public buildings, or a public building doing a bathroom makeover of $10,000 or more, to put in changing tables an adult can fit on.
