Sometimes this week I want you to have a very cozy accident. You are going to wet your diaper while lying in bed - and you are going to make it as cozy as possible. Put on a diaper and over it, put on the most comfortable clothes you have. If you have something special that makes you feel little - like feetie pajamas- put those on.
Get a warm drink ready for yourself. It can be anything that makes you feel cozy- hot chocolate, warm milk, warm apple juice, tea, or even warm water. Now climb into bed and sip on your drink. Now that you are comfortable in bed there's no reason to leave. You don't need to get up to go to the bathroom - just remember that.
All you need to do is relax and feel cozy. As your bladder fills just keep reminding yourself that you are too cozy and comfortable to leave this bed. You don't need to leave this bed after all - you have a diaper on, and that will take care of any accidents. When you feel just the slightest feeling that your bladder is full, let go. Let yourself have a nice relaxing accident in your diaper. Don't worry - you'll be nice and dry and comfortable in bed, so just give in and enjoy the feeling.
