A little brother is usually the youngest brother of more than 1 brothers or sisters who have at least one of the same parents. A little brother is usually the brother that looks up to his older brother or sister asking for advice, and looking to his older siblings for guidance, and other advice needed in life. A little brother can sometimes be the strongest out of his siblings because a little brother is able to learn from his sibling's life experiences and is able to be a couple of steps ahead than those who are older than him. Sometimes the older siblings of the little brother take it upon their selves to compete with their little brother and vice versa, if one or the other feels as if their sibling is getting more recognition or attention than the other. In other households and families little brothers get along great with their older siblings, and only try to help and encourage them.
