In this Nov. 19, 2012 photo, twins Abigail and Noah Thomas, 8, ride on the motorized wheelchair of their mother, Jenn Thomas, on their way to a school book fair in Arlington Heights, Ill. Thomas, a 36-year-old mom who has cerebral palsy, says her twins occasionally complain about having to do a few extra chores around the house to help her. Abigail nods and smiles upon hearing this, but says for the most part, their lives are "kind of normal." For her, having a mom with a disability is just how it is, she said. (AP Photo/Martha Irvine)
