Spartan children were born to serve Sparta. They were in essence ‘children of the state’ not of the parents.
Spartans would only raise babies they believed would be strong and healthy.
When babies were born, they were washed in wine, as it was believed that this would make them strong. Following this, soldiers and elders would visit the household and undertake tests on the baby to see if it had any weakness or infirmity.
If these tests were not passed, the baby would be left out in the wild to die. Sometimes the babies were either left at the base of, or thrown off the cliff of Mount Taygetus.
Boys would leave the house at age 7 and move into barracks to begin their warrior training.
Girls were raised at home to be strong and athletic. They were raised on physical education and athletic competitions.
