The short answer
A baby giraffe is called a calf. It arrives after a ~15-month pregnancy, and because giraffes give birth standing up, the newborn's first experience is a fall of about 1.5–2 metres to the ground — a jolt that actually helps trigger its first breath. A calf is already about 1.8 metres tall and 50–70 kg at birth, and it can stand and run within an hour or two. It needs to: more than half of giraffe calves are lost to predators in their first year, which is exactly why calf survival is the number that decides whether a giraffe population grows or shrinks.
The longest wait, then a long drop
Giraffe gestation lasts roughly 453–464 days — about 15 months, one of the longer pregnancies among land mammals. Females almost always give birth to a single calf, standing, often returning to traditional calving grounds. The dramatic ~2-metre drop sounds brutal, but it is normal and useful: the impact and the sudden exposure to air help clear the airways and start the calf breathing. Within minutes the mother is nuzzling and cleaning her newborn.

Up and running — fast
A newborn giraffe is one of nature's quickest starters. Wobbly at first, most calves are standing within an hour and running within a few hours. This speed is not cute; it is survival. A calf that cannot keep up with its mother, or flee a predator, will not last long on the open savanna.
Calving pools: giraffe crèches
Giraffe mothers don't raise calves entirely alone. In many populations, several mothers gather their young into "calving pools" or crèches — nursery groups where calves rest together while the adults take turns watching over them. This shared vigilance lets mothers browse farther afield while reducing the risk to any single calf. It's one of many signs that giraffes are far more socially organised than their old "aloof loner" reputation suggested — a theme explored in giraffe behaviour and social structure.
Nursing, weaning, and growing up
Calves nurse for several months and gradually begin sampling leaves, following their mother's example. Weaning typically happens over the first year or so, though young giraffes often stay near their mothers well beyond that. Growth is rapid in the early years before slowing as they approach the height of a full-grown adult.
Why calf survival is everything
Here is the fact that ties biology to conservation. Because so many calves are lost to lions, leopards, hyenas, and wild dogs in the first year, the rate at which calves survive is the single strongest driver of whether a population rises or falls. Long-term studies of Masai giraffes — following thousands of known individuals — showed that changes in calf and adult female survival, shaped by habitat quality and human pressure, largely explain population trends.
Save the calves and you save the species. Almost every giraffe conservation gain traces back to more young animals surviving their first year.
That is why threats like drought and habitat loss matter so much: they hit calves hardest, through weaker mothers and less cover. And it is why protecting habitat and reducing pressure on breeding females does more for giraffes than almost anything else.
