Kids who were compared to siblings may spend years measuring their worth against others

"Why can't you be more like your brother?" or "Your sister never behaves this way." For many children, these aren't just passing comments. They become messages that shape how they see themselves for years to come. While parents may compare siblings to motivate better behaviour or performance, psychologists say these comparisons can quietly undermine a child's self-worth, turning home into a place where love feels conditional rather than secure. Over time, this mindset can follow people into adulthood, influencing their careers, friendships, romantic relationships, and even the way they measure success. Here's why sibling comparison can have such lasting psychological effects.
