As a freelance journalist for more than 20 years, Christina started her career as a travel writer. Her travel features have appeared in the Los Angeles Times, the Chicago Tribune, the Boston Herald, and Westways magazine. Her first travel guide, Northern Italy: A Taste of Trattoria, now out of print, was the inspiration for her new travel series, Chow Italy.

With the birth of her fraternal twin sons and subsequent single-born son, her writing focus naturally turned to parenting and family travel. Her parenting features have appeared in Twins magazine, LA Parent, and Parents magazine. She's the author of four books on parenting and twinning including Double Duty: The Parents' Guide to Raising Twins, and Parenting School-Age Twins and Multiples.

In 2004, she started Talk About Twins, a website devoted to twins, twin relationships, parenting twins and their siblings.
