She is the mother of many important deities, such as Pele, Kāne Milohai, Kāmohoaliʻi, Nāmaka, Kapo, and Hiʻiaka.
[1] With the help of a magic stick called the Mākālei, Haumea repeatedly transforms herself from an old woman to a young girl, and returns to her homeland periodically to marry one of her offspring, thus giving birth to continuous generations of humans.
In a story, she visited Muleiula, the daughter of a chieftain who was experiencing painful childbirth, during which she discovered that humans only gave birth by cutting open the mother.
Seeing this, Haumea created a potion out of the Kani-ka-wī tree (Spondias dulcis), which allowed the mother to push out the baby naturally.
[1] Some traditions identify Haumea with Papahānaumoku, the goddess of the Earth, and wife of the sky god Wākea.
