How to wear The Diaper

Signs it's time to...

Size up

(*) Waist sits more than 2 fingers below the belly button
(*) Tabs barely close at the edges of the landing zone
(*) Leaves lasting red marks or indents on the waist and thighs
(*) You experience an increase in leaks, blowouts, and tears, especially overnight

Size down

(*) Sags around the legs, leading to leaks
(*) Gaps at the waist
(*) Tabs close together or overlapping—tightening the waist to a point where the tabs overlap may “solve” waist gaps, but will cause leg holes to bunch and feel uncomfortable (like a belt that is too tight on big pants)
