I insist on large bags of diapers/pullups to be left at my house and I tell the parents when I need more. I do not accept the two in the bag each day method. Somedays child needs more than others and I need control. And especially when training because I take them usually every hour - hour/half and if they have already wet the pullup then it means changing them. Usually after wasting a bag quickly with this the parents back off and say ok lets wait a bit and bring me diapers instead.
