[/INST] HiT hanks for using Chat Doctor Sibling rivalry is the jealousy, competition and fighting between brothers and sisters.  It is a concern for almost all parents of two or more kids. Problems often start right after the birth of the second child.  Sibling rivalry usually continues throughout childhood and can be very frustrating and stressful to parents.  Better to consult a psychologist in this case. Thanks </s>
