ST:TNG:133 - "Rascals" (Stardate: 46235.7) - this is the 7th episode of the 6th season of Star Trek: The Next Generation.
While en route back back from visiting a planet, a shuttlecraft carrying Picard, Ro, Guinan, and Keiko O'Brien are caught in an energy field and is about to explode. Chief O'Brien (in his last real-time performance on TNG before transferring to DS9) is able to transport them back to the Enterprise after some difficulty, but now they are children! Though their minds remain intact, they have the bodies of 12 year olds. Soon, they are relieved of duty until a cure can be found. When Dr. Crusher does find one, before she can implement, 2 Klingon warships attack the Enterprise and at the same time Ferengis materialize onboard and seize the ship! Now it's up to the "children" to find a way to free the Enterprise!
Trivia note: the "kids" (who do a great job acting like their adult counterparts) include David Birkin as the young Picard (he also played Picard's nephew in "Family"). Guinan states her father is 700 years old. Hana Hatae begins her role as Molly, the daughter of Miles and Keiko O'Brien (she would reprise her role throughout Deep Space Nine).
Also, this episode is directed by Adam Nimoy, the son of Leonard Nimoy (aka, Spock).
