Sweet Children is the third EP released by punk rock band Green Day. It was also Billie's and Mike's first band with John Kiffmeyer on the drums, where Billie wrote his first song, "Why Do You Want Him". It is a collection of some of the band's earliest songs that they were still playing live at the time. It was recorded in 1990, in Minneapolis, Minnesota while the band were on a brief break from their summer tour, and released on seven-inch vinyl. Due to a typo on Green Day's website, many believe that this record was released in 1987, a year before Green Day had even formed. What makes it believable is the rough sound and poor mixing of the recordings. The EP was released on Minneapolis-based indie label Skene! Records. These were the last recordings drummer John Kiffmeyer would appear on. Shortly after the end of the tour, he left the band to attend college.

There are four different pressings of the EP (some limited quantities included two different variations of red vinyl), which has been out of print since its inclusion on the CD issue of Kerplunk! in 1992. Because of this, it has since become a valuable and sought-after item among collectors and Green Day fans alike.

The first pressing's cover is a picture of Mike Dirnt's leg during a concert.

The second pressing's cover is a black and white picture of a somewhat trashed Volkswagen Beetle with the caption "What Do You Think Mike..." This rare second pressing, limited to 600 copies as opposed to the first run's respectable 1,500, also featured a handwritten insert, reading "Not a lyrics sheet, so don't get your hopes up".

The third pressing is the same as the one above in every way except there is no insert, and the cover, instead of being black and white, is tinted red.

The fourth pressing is obviously a reissue from possibly 1991, for it features a mostly blank cover with a picture of the band, and a rather long summary on the back of the sleeve, which explains how these songs are also on Kerplunk!, so this must be a reissue of the EP.
