Women of the Walbiri tribe are not to bear children until they are at least seventeen years of age. Pregnancy changes very little for the Walbiri women. They continue their everyday chores and activities right up to the day of the actual birth of their child. However, the aboriginal women must follow strict dietary restrictions through their pregnancy and until the child is three years old. Because they breast feed the child until it is three, dietary restrictions are to ensure that the mother is correctly nursing the child.
Birth is an important event to the Walbiri because infant mortality rates are so high.
Due to infant mortality rates being so high a child is not named until the age of two. At this age it is believed that the child will live, having survived all illnesses.
