Rivalry occurs between most, if not all, siblings to a varying degree. Rivalry may be manifested as a verbal or physical attack, frustration, persistent demands for attention, or as regressive phenomena. When handled properly, healthy competition among siblings will lead to the acquisition of social, interpersonal and cognitive skills that are important to the development of the child. Mismanagement of the competition may lead to psychological problems later in life. The appropriate spacing of children and the preparation of existing children for a new sibling help to reduce sibling rivalry. Family situations that will potentially lead to jealousy should be avoided. Parents should not make comparisons between siblings and favoritism should be avoided. When episodes of sibling rivalry develop, the cause rather than the manifestation of the rivalry should be treated. Patience, love, understanding, common sense, and humor are important parental skills necessary to minimize sibling rivalry.

Background: The coronavirus disease (COVID-19) pandemic spares no nation or city, and the virus is responsible for the escalating incidence and mortality all around the world. Objective: This article reviews the impact of “Long Covid” on Children. Methods: A PubMed search was conducted in December 2021 in Clinical Queries using the key terms "COVID-19" OR “long COVID”. The search was restricted to children and adolescent aged < 18 years, and English literature. Results: Many large-scale studies have provided strong scientific evidence as to the detrimental and irreversible sequelae of COVID-19 on the health, psychology, and development of affected children. Many insights to the management of this disease can be obtained from comparing the management of influenza disease. COVID-19 is generally a mild respiratory disease in children. Several syndromes such as multisystem inflammatory syndrome in children (MIS-C) and COVID toe are coined but are probably not specific to SARS-CoV-2. “Long COVID” or the long-term effects of SARS-CoV-2 infection, or the prolonged isolation and containment strategies on education and psychosocial influences on children associated with the pandemic, are significant. Conclusions: Healthcare providers must be aware of the potential effects of quarantine on children's mental health. More importantly, health care provides must appreciate the importance of the decisions and actions made by governments, non-governmental organizations, the community, schools, and parents in reducing the possible effects of this situation. Multifaceted age-specific and developmentally appropriate strategies must be adopted by health care authorities to lessen the negative impact of quarantine on the psychological wellbeing of children.
