Sibling rivalry is the intense feelings of competition and jealousy that sometimes characterise the relationships of brothers and sisters. Would it be too far off the mark to suggest that these feelings are often inadvertently caused by parents themselves? While parents do not go all out to promote rivalry between siblings, often it is their passing comments and acts of omission that cause a child to see a sibling as a rival.
Parents may, often inadvertently, lean towards one of their children due to various reasons. This could be because this child is especially gifted and brings them unlimited bragging rights, or because this child is particularly well-behaved when compared to an unruly sibling.
