A baby carriage on Sigma Iotia II, 2269
A baby carriage was a wheeled vehicle used to convey babies.
In 1968, a couple were walking down a sidewalk of East 68th Street, in New York City, with the father pushing the carriage. (TOS: "Assignment: Earth")
In 2268, a female Iotian pushed her baby in a carriage down the streets of the Southside Territory. Karf inspected it to make sure she wasn't hiding anything suspicious. (TOS: "A Piece of the Action")
