'die Jugend' and 'das Kindesalter' both talk about early stages of life. But they refer to different periods. 'Das Kindesalter' begins at birth and lasts until the beginning of puberty. 'Die Jugend' comes after that and lies between childhood and adulthood. Learners may confuse the words because neither refers to adulthood. When talking about small children, 'Kindesalter' fits. When talking about teenagers or the time of growing up, 'Jugend' fits.
