Wisconsin parents Shawn and Shannon thought it would be fun to have a baby. They were only 18 at the time, and were stunned to discover that Shannon was pregnant with twin boys. The early years with Bryce and Brandon were relatively easy with the help of both sets of grandparents, but now those days are a distant memory, with the addition of a daughter to the mix. The twins, now four years old, have outgrown toddler stage and know how to flip their parents the bird, hit, kick and curse like sailors when they are told "no." Their baby sister, Brenna, 18 months, is often the victim of their violence, and she mimics her brothers' aggressiveness, hitting them as well as other children. Mom and Dad know they were passive for too long, but now they're begging for help and don't know where else to turn.
