LANCASTER, N.Y. — CamerynLee was only 3 years old when her father, Lance Cpl. Eric J. Orlowski, a Marine Corps reservist, was killed in an accidental shooting during the first days of the Iraq war. Now 8, she is suddenly hungry for information about the man she remembers only in sketchy vignettes: Did he like chicken wings as much as she does? How about hockey? Was he funny?

“When it happened, I don’t think she fully understood,” said her mother, Nicole Kross, 29. “At that age she really didn’t ask too many questions. It’s all coming out more now.”

In a grim marker of the longevity of the war, children who were infants or toddlers when they lost a parent in action are growing up. In the process, they are coming to grips with death in new, more mature and at times more painful ways — pondering a parent they barely knew, asking pointed questions about the circumstances of the death and experiencing a kind of delayed grief.

Families and bereavement counselors say that media coverage of the war, dedication ceremonies and even school events — in which most classmates have both parents in attendance — can all heighten yearning for the missing parent. For young children, the flood of prickly feelings and questions often arises just as the surviving parent is moving beyond his or her own intense grief, sometimes with a new spouse or partner in the picture.
