Abandoned Baby Carriages

I can't decide if discarded baby carriages symbolize anything not already symbolized by other types of garbage. An abandoned baby carriage does not, after all, represent an abandoned baby.

It could be said to symbolize the passing of infancy and the march of life to adulthood, or the cavalier disposal of the things of a child.

On the other hand much of this type of equipment comes with expiration dates, meaning it should be discarded at some point to reduce the risk of safety hazards.
