Having a younger sibling who is taller and stronger can have both positive and negative effects on relationships and self-esteem.
On the other hand, it can also foster a sense of admiration and respect for the younger sibling's abilities. Older siblings may learn to appreciate and support their younger sibling's strengths, leading to a stronger and more positive relationship.
