Teresa Giudice: 'I Wish I Could Do Everything Differently'

— -- Teresa Giudice starts her 15-month jail sentence for fraud on Jan. 5.

But the mother of four considers the upcoming time behind bars as a learning experience.

"I wish I could do everything differently," Giudice, 42, told US Weekly for this week's issue. "But then again, maybe not, because this is a life lesson that I need to learn and will learn, and will teach my children for the rest of my life, just as Judge Salas told me she expected me to do."

U.S. District Court Judge Esther Salas had some parenting advice for the reality star last Thursday during her sentencing.

"Your four daughters need to understand discipline. If you don't have it, you shouldn't spend it," she said in court. "If they won't like you because you're not driving a Benz or walking on Jimmy Choos or Manolo Blahniks, then they're not your friends."

The judge also staggered Teresa's sentence with her husband Joe's three and a half years. They have four daughters: Gia, 13, Gabriella, 10, Milania, 8, and Audriana, 5.

In a special interview for Bravo, the network that airs their show, the Giudices spoke of concern for their daughters after the sentencing.

"All I keep thinking about is my daughters," Teresa said. "I can’t imagine not being there. They need their mom.

"I'm grateful to the judge, she could have taken us yesterday if she wanted," she added. "I'm going to do fine [in prison]. … I just want to make sure my daughters are OK. I just want to talk to my daughters every day. I want him to bring them to me."

She told Joe, "Just make sure you come once a week."
