Time you let film sit in camera.

I ‘m only just learning about Polaroid cameras but i feel like I’m wasting a lot of film by just letting the film sit in the camera.

Should i be pre pared to use a whole cartridge of film when i use my camera because at this rate i only you it on weekends and to get a good photo its like the film isn’t developing properly?

Note: its an Australian summer where the weather and temp at the moment is all over the place
