ABSTRACT
There has been a steady increase in the number of live multiple births in the developed nations over the last few years due to healthier populations, medical advances and fertility treatment, and social changes which have led many women to delay starting their families or continuing to bear children at a later age-there has been found to be a direct correlation between the age of the mother and the chance that she will conceive dizygotic (DZ), non-identical, twins (Lazar et al. 1981). Correspondingly, there has been a growing public interest in multiples and an awareness by professionals that they need to be better equipped to offer help and advice to parents and twins alike. This book collects the accumulated knowledge of leading professionals on the subject of multiples and how they may differ in their needs from singletons in the current social environment.
