Family who have had a set of IVF triplets - each born two years apart - celebrate their first Christmas together

Karen and James Marks are in the midst of preparing for their family's first Christmas Day with their three children - Cameron, five, Isabella, three, and Gabriella, 17 months. The three youngsters are considered triplets as they were conceived on the same day - and at the same time - through IVF, from the same batch of embryos.
