We do. You are renting the diapers from us, and we expect them back upon termination of service. We will assess diapers for damage at every year after your initial start date, and replace damaged (not stained) diapers for free. If there is damage to the diaper before the year is out, or in between assessments, we will bill you the $7.50 it costs for a new diaper. These diapers are meant to last for a long time. Any lost diapers will also be charged to you, at the $7.50/diaper rate.
