The parents of a pre-kindergarten student nicknamed "Tater Tot" are battling a suburban Dallas school's decision to segregate their son because his long locks violate the district dress code.

Taylor Pugh again found himself facing in-school suspension on Wednesday. The Mesquite school district is keeping Taylor in the library apart from his classmates because his floppy hair falls in his eyes and extends below his earlobes and shirt collar.

The school district says all students must adhere to the code of conduct.

But Taylor's parents say they won't cut his hair, even after they said the school principal threatened to permanently suspend their 4-year-old son from school.
