Right after the split-up of his band named Regard in 2002, Sap~hire set up Sleeping Children. (which name refers to children, that is to say to carefreeness and sleep, in a single word to ephemeral protection) But this is only during February 2003 that Sap~hire met Murmur, the first singer, during a gothic party washed down with plenty of alcohol. Crepuscule, the band first guitarist, joined Sleeping Children right after the first rehearsals. In May, the band recorded In Vivo Test.
