1. A system comprising:
a liquid administration device; and
one or more inserts;
wherein the liquid administration device comprises a body configured to contain and support a medicament container;
wherein the body comprises a wall;
wherein the liquid administration device comprises a proximal end and a distal end, with a longitudinal axis extending from the proximal end to the distal end;
wherein the medicament container comprises an initial quantity of a medicament;
wherein the wall of the body comprises a viewing window in the form of an aperture;
wherein the aperture has a longitudinal dimension parallel to the longitudinal axis of the device;
wherein, when the medicament container is contained and supported by the body, the viewing window is coincident with the medicament container such that the medicament is visible through the viewing window; and
wherein the aperture is configured to receive the one or more inserts, wherein the one or more inserts, when received by the aperture, reduce the longitudinal dimension of the aperture so as to partially obscure the aperture and hence reduce the size of the viewing window prior to the medicament being dispensed from the medicament container.
