I've been wearing for so long that my bladder does it's own thing once I'm taped up. Most of the time it's in little spurts, but there's always a flooding after going out to eat (DARN YOU SWEET TEA!!!) lol. I know the max capacity of MOST of my diapers, and how bulky they can get (I've been surprised a few times.)
To keep bulkiness in check, I have to change more frequently if I'm wearing leggings, tight jeans, or (In summer) short shorts. I think that's why I enjoy wearing in winter more. I can wear a thicker diaper and flood it to the max with all the layers I have on and nobody notices.
