On the tombstone on the Cakir family, Süleyman Cakir's year of birth is written as 1964, his sister Derya's as 1974, and his mother's as 1951. According to this, his mother gave birth to him at the age of 13. Also, in a flashback scene of the Cakir siblings selling steamed rice and chickpeas on the street, Süleyman and Derya Cakir are both little kids. Having an age difference of 10 years, one must be at least a teenager when the other is a little kid.
But in 1964, a 13 years old mother is not unheard of in the region. Also, the majority of children were given late birthdays to avoid a fine. So 1951 might be a wrong date which was only provided by the parents to the government.
