Giraffes usually mate and have baby giraffes once they reach 3 years old to 4 years old.
When giraffes reach 3 to 4 years old the giraffe reaches sexual maturity which is when they begin mating and having sex and making babies.
Some giraffes have babies as early as age 3 years old while other giraffes may not be ready to have babies until around 4 years old.
Most giraffes have around 10 baby giraffes in it's lifetime.
The way that giraffes give birth to baby giraffes is give birth is while standing up so a calf giraffe enters the world from quite a height.
The baby giraffe will fall 6 feet to the ground with hooves and head first and then after the giraffe calf drops to the ground, the mother giraffe will begin to clean it off, and after a few minutes, the giraffe calf will attempt its first steps.
