Baby Running Wild is the ninth domestic single by the Japanese hip-hop group Lead. The single charted in the top twenty on Oricon at #11 on the Oricon Singles Charts, remaining on the charts for three consecutive weeks.^[1]

Baby Running Wild became their second single to be released as both a standard CD and a CD+DVD combo, although the latter edition was of limited release.^[2][3] The other single to contain a combo edition was Night Deluxe, which was released a year prior.^[4]

The title track was written and composed by Japanese musical composer and lyricist Satori Shiraishi.^[5] The coupling track, "Summer Splash," had its lyrics written by Shōko Fujibayashi, who had worked with Lead for their song "Night Deluxe" the previous year. The arrangement and composition was performed by Akira Sasaki.^[6]

Baby Running Wild became Lead's second single to be released as both a standard CD and a CD+DVD combo. The CD+DVD was of limited edition, while the CD is still available. Both editions held the same material on the CD: the title track, the b-side "Summer Splash", and their corresponding instrumentals.

However, instead of carrying the making video to "Baby Running Wild" like "Night Deluxe," the DVD contained the music video. The video would later be released on their compilation DVD Lead Movies 3 in 2008.^[7]
