When my son was born, my father-in-law gave him a female camel calf. This is in line with Somali tradition where 'waxad' or gift is given to newborns (boys).
The purpose is two-fold; one to start growth of the child's own herd. Two, it is meant to see if the child has 'farhad' (luck) or is 'bacow' (unlucky) depending on whether the female calf grows into adulthood and produces more camels for him.
