An older brother is a male sibling who is born before another sibling. He often takes on a protective role and may help guide younger siblings through various life experiences. Older brothers can influence their siblings' interests, hobbies, and social skills, serving as role models or mentors. In many families, older brothers share responsibilities, such as helping with chores or looking after younger siblings. They may also engage in playful activities, fostering a bond that can last a lifetime. The relationship between siblings, including older brothers, can significantly impact emotional development and family dynamics.
