The birth of twins can be an exciting and challenging experience for a family. However, circumstances unique to the relationship between the twin and the family and the relationship between the twins themselves may exacerbate existing problems or create new ones. Parents are often overwhelmed by the amount of time and work involved in caring for the twins, and other siblings may feel excluded from the family. Twins themselves may have difficulties with processes such as individuation and bonding with other family members. With supportive anticipatory guidance, physicians can help parents and siblings of newborn twins adjust to the special circumstances that the birth of twins can bring.
