Kenyatta was raised according to traditional Kikuyu custom and belief, and was taught the skills needed to herd the family flock. When he was ten, his earlobes were pierced to mark his transition from childhood. Wambui subsequently bore another son, Kongo, shortly before Muigai died. In keeping with Kikuyu tradition, Wambui then married her late husband's younger brother, Ngengi. Kenyatta then took the name of Kamau wa Ngengi ("Kamau, son of Ngengi"). Wambui bore her new husband a son, whom they also named Muigai. Ngengi was harsh and resentful toward the three boys, and Wambui decided to take her youngest son to live with her parental family further north. It was there that she died, and Kenyatta—who was very fond of the younger Muigai—travelled to collect his infant half-brother. Kenyatta then moved in with his grandfather, Kongo wa Magana, and assisted the latter in his role as a traditional healer.
