what is the point of putting diapers on the babies if the parents just soil their pants anyhow? Is it that different if the baby pess on you or you pee on yourself?

And, I want to know if the diapers are disposable or if they are the old cloth kinds, and if they are the onld cloth kinds, where do they get those ginormous safty pins???
