The baby was born over the weekend to Dr. William Petit and his wife Christine.
The former Christine Paluf met Petit while volunteering for the Petit Family Foundation. William Petit created the charity in memory of his wife Jennifer Hawke-Petit and their daughters, 17-year-old Hayley and 11-year-old Michaela.
The family was held hostage for hours and their home in Cheshire set on fire. William Petit was severely beaten but survived.
Petit and his new wife announced shortly before their first wedding anniversary Aug. 5 that they were expecting a child.
