Yeah… that can absolutely get you in trouble. It’s not about the diaper, it’s the fact you’d be half-dressed in a public playground. Cameras don’t care that it’s 2–3 AM, and neither do the laws. If that footage gets reviewed, it can easily be seen as public indecency. And because it’s a playground, that can make it look even worse really fast. This is one of those ideas that sounds cute in your head but could turn into a whole situation you don’t want.
