Then she gets to do it all over again the next day.  Rooney is one of about 3.9 million student parents working on their undergraduate degrees in the United States. Nearly half those students are single parents and work full-time jobs, according to a 2011 report by the Institute for Women's Policy Research.  While it can be a nightmare to squeeze in class, work and parenting responsibilities in a single day, the students somehow manage their chaotic schedules.  "It's crazy," laughs Rooney while describing her daily routine. "You probably wouldn't even believe it."  The biggest challenge for many student parents is finding adequate child care services on campus -- unless, of course, professors don't mind screaming babies interrupting their lectures.  There is one child care spot for every 10 student parents who need services. The number of centers at two- and four-year institutions has decreased in the past eight years, which leaves student parents on a college budget with few options.  Rooney receives a scholarship that covers the $800 child care costs for her son each month. But the grant doesn't extend to the summer, which poses a problem for the 28-year-old math major, who needs to take summer classes to graduate on time next year.  "It's just a juggling act with trying to find someone every day who will babysit my kids so that I can go to class and go to work," she said.  Rasheedah Phillips had her daughter Iyonna at age 14. But that wasn't going to stop the single mom from attending Temple University, where she majored in criminal justice before enrolling in Temple's law school. Phillips said she comes from a family of teen moms -- including her mother, grandmother and several relatives.  "When I then became a teen parent, really my motivation was to not continue that cycle in my family and to give my daughter more opportunities and a better chance than I had to not repeat those same circumstances," she said.
