Woman on IVF pregnant with second set of quads

AN AUSTRALIAN mother due to give birth to her second set of quads in a possible world-first has a 50% chance of delivering prematurely or with abnormalities, an IVF specialist said.

The four babies are due in December when the first set of siblings are 16-month-old toddlers.

Dale Chalk, 26, of Brisbane, gave birth to two girls and two boys in August using in-vitro fertilisation.
