Older brothers are sometimes left in charge of younger brothers and sisters (in the role of a babysitter, as it were), especially during times when the parents are both absent. They can also play a vital role in the discipline of their younger siblings, as the child is more likely to obey a big brother rather than a big sister, because of the brother's superior strength
In Japanese based references, Oniisan or Ani can refer to older brothers and otouto can refer to a younger brother.
