The parents of Brooke Loeffler, a kindergartener at Olympia Elementary School in Universal City, said they have a new baby at home and they are having difficulty adjusting to a new schedule, KENS-TV, San Antonio, reported Wednesday.
Brooke was forced to spend lunchtime in detention as a result of her three tardies, the family said.
"It was my responsibility to get her ready and get her to school," her father said. "I failed that responsibility a couple of times. It makes me sad to see my daughter upset for something she doesn't understand."
District officials said the policy has cut down on tardiness at the school.
"They have been able to cut down the number of tardies way back -- as much as 90 [percent] to 95 percent of the tardies," said Steve Linscomb of Judson Independent School District.
Loeffler's parents said they want the district to change the policy, so parents are penalized instead of children.
