Christians are fleeing militant Muslims. There is a very high likelihood this is a Christian child.
Possible. If so he was likely thrown overboard by the Muslims on the boat.
There hasn't been a Christian living in Kurdish areas of Turkey or Syria since the Ottoman (Islamic) Caliphate used them as auxiliaries in the Genocide against the Christian Armenians.
And generally, as the incident of Muslim "refugees" throwing Christians overboard on their way to Italy shows... Muslim "refugees" and smugglers do not allow Christian refugees to flee in this flood of invading Muslims swarming into the Europe of receding Christianity.
