Jesse James: Strain of Divorce for Daughter Sunny

Jan. 28, 2011 — -- Now that Jesse James is planning nuptials with tattoo artist Kat Von D, his youngest daughter, Sunny, 7, is preparing for stepmom No. 3.

The motorcycle man confirmed to The Associated Press last week that rumors concerning his engagement to Von D were true. It will be marriage number four for James.

His many marriages have kept the notorious biker bad boy in the spotlight, but the multiple wives and exes may be taking their toll on his youngest child, who at age 7 may be bounced between her biological mother, ex-con Janine Lindemulder; the mother of her half-siblings, Karla James; Sandra Bullock, who was Sunny's primary caregiver until her divorce from James in June 2010; and Kat Von D.

"Divorce is always disruptive for kids and it's an unfortunate situation for kids who have to go through this more than once," says Dr. Alan Hilfer, chief psychologist at Maimonides Medical Center in Brooklyn, N.Y. "This kid's going to be in for a bumpy ride."

Calls to Bullock's and James' representatives, and Lindemulder were not returned.

Though Sunny may be a high-profile case of a child with "multiple mommies," given that 46 percent of marriages in the U.S. involve a remarriage for one or both spouses, it's not uncommon for today's children and teens to face the adjustment of having one or more step parents.

ABC News asked child and adolescent psychologists to weigh in on how to smooth the ride for kids making such a transition.
