An Anderson County mother says her daughter died days after celebrating her seventh birthday.

Channa Kelly said her daughter, Alexandra Hope Kelly, was popping her birthday balloons with scissors when she left the room to lie down. But when she returned to the living room, she found Alexandra face down.

Authorities have not yet determined the cause of death for the child.

Authorities say the situation remains under investigation.

No further information was released by law enforcement.

The U.S. Consumer Protection Safety Commission (CPSC) says balloons are the leading cause of suffocation deaths in children of all kids’ products. Children can also choke on uninflated balloons or balloon pieces of after it’s popped.

Because of the danger of suffocation, the CPSC recommends that parents and guardians do not allow children under the age of eight to play with uninflated balloons without supervision. The CPSC does not believe that a completely inflated balloon presents a hazard to young children. If the balloon breaks, however, CPSC recommends that parents immediately collect the pieces of the broken balloon and dispose of them out of the reach of young children.
