Families with twins occasionally confront unique problems warranting considerable professional attention. The possibility that twins may be less likely to be admitted to private schools of their choice, due to reduced financial contributions from family members, was recently raised. Specifically, two twin children have two sets of grandparents, while two non-twin children have four sets of grandparents; thus, schools would profit more highly by admitting non-twins. This sets the stage for reviewing steps that some universities and businesses have taken to offset the financial burdens of rearing multiples. Next, a research review of four twin studies follows. Findings on gluten sensitivity, tremors, communicative adaptability and serological differences are summarized. A tour of a fascinating twin exhibit at the Teylers Museum, in the Netherlands, concludes this column.
