A baby llama is called a “cria” which is Spanish for baby. It’s pronounced KREE-uh. Baby alpacas, vicuñas, and guanacos are also called crias. Mama llamas usually only have one baby at a time and llama twins are incredibly rare. Pregnancy lasts for about 350 days, nearly a full year. Crias weigh 20 to 35 pounds at birth.
