A Tough Time
A female zebra is known to carry their baby for approximately 12 to 13 months. After this time, the zebra is required to separate from her family and herd and birth the baby on her own, and away from predators.
Comfort
Pregnant zebras are similar to pregnant humans, as they both find comfort in having someone supporting them while they are giving birth. Just having someone there provides the birthing mother with much-needed security, strength, and support. It’s what most mammals want.
