In 1960, Gene Deitch produced 13 cartoons for MGM at his studio, as most of his shorts were widely panned and considered to be the worst of Tom and Jerry for a number of reasons from fans, with the exceptions of The Tom and Jerry Cartoon Kit, Carmen Get It!, and Buddies Thicker Than Water.
When his unit closed down, Chuck Jones produced 34 more at his studio before being shut down in 1967, ending production of Tom and Jerry cartoons.
Babysitter Jeannie (voiced by Julie Bennett) is instructed to look after the baby while his mother (also voiced by Julie Bennett) goes out. However, Jeannie pays more attention to talking on the telephone apathetically than her actual babysitting. In the midst of Tom and Jerry's usual fighting, they see the baby crawling out of its pram. Any attempt to return the baby to where it came from simply results in the baby escaping from the pram again. During one escape, the baby crawls into Spike's dog house. Tom accidentally grabs Spike instead of the baby, and is promptly attacked, scratched and bit. This time, Tom angrily brings the baby back to Jeannie herself, who hits Tom over the head with a broom, thinking that Tom has taken the baby away from her.
Realising that the baby is no longer worth the trouble, Tom does nothing the next time that it crawls from its pram. However, he and Jerry are forced to react after the baby crawls down to the street and into a construction site. The baby crawls from one steel beam to another while the cat and mouse look on. Jerry manages to catch up, and saves the baby from crawling off a wooden plank by grabbing his diaper. The diaper comes loose, and the baby falls, but he is then caught by Tom. Tom attempts to put the baby's diaper back on, but in the impending confusion, ends up putting the diaper on himself while the baby crawls off, nonchalantly.
Tom and Jerry catch up with the baby, only to lose it again, and fearing that it has crawled into a cement mixer, the cat and mouse dive straight in, only to find that the baby never did enter the mixer but instead playing with a hammer. The baby then playfully bonks Tom on the head.
Later on, Jeannie is in panic and crying, telling a police officer that she was babysitting, took her eye off the baby for "one teensy minute" and the baby was gone. Tired, Tom and Jerry arrive with the baby. Jeannie grabs the baby while the two try to escape, but the police officer (voiced by Bill Thompson) arrests Tom and Jerry, assuming that they were the "baby nappers". In the police car, the police officer cannot believe Tom and Jerry's explanation. Just then, to their surprise, the baby crawls past the police car and away into the distance.
- Jeannie: Yes Ma'am.
- Jeannie: Goodbye. Hi it's me, Jeannie. Oh no I'm babysitting for two hours oh hehehe he's silly oh oh I did yeah I have a date already oh no you kidding she wouldn't do that.

- Jeannie: I just turn my back for one teensy minute, and she's oh and the baby was gone! Oh please officer you must get that baby back you-- There's the baby!
- (Tom and Jerry arrive tired holding the baby and Jeannie grabs the baby. Tom and Jerry try to escape, but the Police Officer grab them)
- Police Officer: Gotcha, ya babynappers. [Tom and Jerry are now in the police car that the police officer is driving. The light changes from green to red as the sign changes from "GO" to "STOP" and the police car stops] A baby crawlin' down the street?! Now who would be after believin' that?! [Just then, to their surprise, the baby crawls past the police car and away into the distance, as the cartoon ends.]
- This features the final appearances of Joan and her baby. This also marks the final appearance of Jeannie, who was hated by fans due to her character often bordering on neglecting her job as a babysitter.
- Joan's husband George is absent in this cartoon.
- This marks the last of a few things:
- The final Tom and Jerry cartoon to be produced in Cinemascope as the Gene Deitch and Chuck Jones era returned to the Academy format used from 1940-1955.
- The final Tom and Jerry production to be produced in Widescreen until Tom and Jerry: Blast Off to Mars.
- The last episode to use the Classic MGM sound effects until the Chuck Jones cartoon, Ah, Sweet Mouse-Story of Life.
Pan and Scan to 4:3 version's reception
The pan-and-scan version of this short was heavily panned by fans, as many important elements are cropped out, such as near the end, Jeannie takes the baby out of Tom's hand is not shown, but shows the baby being removed from Tom (looks as if the baby vanished out of nowhere).
This short is unpopular with fans, and often considered to be a weak end to the 1940-1958 era of Tom and Jerry. This is mainly due to the lack of slapstick in its plot, Jeannie's negligence of taking care of the baby (which is even worse than in Busy Buddies) and the ending where Tom and Jerry get falsely arrested by a police officer (who accuses them of baby napping).
- This short were banned in Morocco because of the arrest of Tom and Jerry, their going to the police and the child's victory.
