A mother and father say their child suffered a concussion in a fall from a high chair at a Gwinnett County daycare, Channel 2 Action News reported. And the matter has drawn state investigators’ attention.

A surveillance video from the Meliora School of Lawrenceville that was shared by Keyatta Smith and Gerald Moon shows the situation involving Karissa, 11 months old, Channel 2 reported. It shows two of the three teachers in the child’s classroom, the station reported. Their backs are turned to Karissa, who is sitting unstrapped in a high chair. The teachers rush to pick up the child after her head hits the floor, Channel 2 reported.

The daycare owner declined to discuss the situation with the station over the phone. However, the director, who did not show her face on camera, said the child got upset, kicked her tray and fell out of the seat, the station reported.

“State guidelines say you can either have a strap or a device for the children sitting in the high chairs,” the director told Channel 2. “In this case, the tray was serving as the device. So we were following state guidelines.”

A state investigator was at the Meliora School on Tuesday, Channel 2 reported.

The parents still don’t understand the explanation.

“I checked the latch myself,” Moon said. “And it has a guard. Ain’t no way in the world my baby could’ve taken her feet and kicked it open.”
