If you are going to be wearing a diaper on the day of your period, do you use the diaper for your sanitary protection, place a pad inside the diaper or use a tampon with the diaper?
I usually wear diapers 24/7, so yes it does include that time of the month. Actually diapers make things a little easier as I am not so focused on worrying about is it time to change my pad/tampon. I think even if someday I decided to give up my diaper play that I would continue using them during my period.
