Curtis initially was charged with first-degree injury to a child, punishable by up to life in prison. Prosecutor David Sheffield says Curtis now faces a second-degree felony, punishable by 2-20 years in prison.
Sheffield told KFDM-TV that it would have been difficult to prove the first-degree felony because jurors might not believe the burns were severe enough to warrant the charge. Curtis remains jailed on $500,000 bond.
Curtis previously said the girl was acting up as he gave her a bath, when her mother wasn't home.
