Language rules at songs are absolute unneccesarily, and harmful. Children can sing at a learned language, for example, the song "Girls and Boys" originally was in English, performed by the children who performed at the contest. By the way, this song in English is by far better. The song "Sensatsiya" is better in English than Russian, and the performer did not sung a word in her native language, all the song was in learned languages. Malta, Great Britain and North Ireland, Ireland, etc. can sing fully in English, this is not fair.
