Officials are urging parents of newborns to stop using popular infant head-shaping pillows.

According to officials, the pillows are not FDA approved and the agency actually does not recommend using them.

The pillows have an "indent or hole in the center" that cradles an infant's head while the child lies on its back.

The FDA says the head-shaping pillows have NOT been shown to be effective to prevent or treat flat head syndrome.

Officials say the pillows create an unsafe sleep environment for babies.
