Babies may be nursed by any lactating female. Adolescents baby-sit while the mothers feed. Photos like this were difficult to get, because the older animals would normally place themselves between us and the young. Calves are dependent on their mothers' milk for at least 3 years. This one will reach sexual maturity in 10-14 years and adult height and weight in about 25.
Growth is continuous throughout life, slower in females but steady in males.
