"Little Children" is a song written by J. Leslie McFarland and Mort Shuman,[1] and was recorded by Billy J. Kramer & the Dakotas.
The lyric concerns a man's entreaties to his girlfriend's young siblings not to reveal his courtship of their elder sister and to leave them alone.
At some points he even bribes them with such things as sweets, money and entertainment on the condition that they "keep a secret".
As such, it was a departure from the traditional love songs previously recorded by Kramer (sometimes supplied by Lennon & McCartney).
[2] When offered another Lennon and McCartney song, "One and One Is Two", for his next single by the manager of both groups, Brian Epstein, Kramer turned it down and chose "Little Children" instead, after a search for suitable material from music publishers.
