Giraffes reach sexual maturity at 3-4 years of age, although, in the wild, males may not breed until ages 6 or 7, due to a system of hierarchy among bulls. Breeding can occur at any time of the year. Gestation is usually 13-15 months.
Giraffe calves grow about 3 centimetres tall each day during the first week and double their height in their first year. By the age of one year giraffe calves can measure 10 feet tall. Giraffe calves are weaned at one year and become fully independent by 15 months of age. Female giraffe calves are fully grown by age five and male giraffe calves by the age of seven.
