     Happy final big diaper Friday of 2021. Crinkles to many more 2022 BDFs. I'm going to Bed now all fresh and clean and double boosted.

     Broke: BDF is for indulging in pamps after a long diaperless week
     
     Woke: BDF is called that because it marks the day of your weekly change. No one can argue that yours have gotten rather big this week~
