Diaper punishment

My brother and I still wear diapers to bed every night. Our parents believe in the "just in case" rule. They say that if we need to use the bathroom we can just use our diapers and then go back to sleep because that's what they are for. Its interesting that they don't really care if our diapers are dry or wet when we get up in the morning. They say its better for us to be diapered and get a good nights sleep without disruptions
