"Les enfants appellent le cheval."
Translation:The children are calling the horse.
'Kid' is often accepted however. It was once explained in a discussion that in that particular case, 'kid' was not accepted because of the formal nature of the sentence itself. This is not a formal sentence. It should be allowed or disallowed across the board. I like to write a lazy 'kid' and move on because typing 'children' is a lot more work! ;D
