Elouise Wade-Meria Taylor, 51, of 53 Saint Johns Church Road, is accused of injuring the child on Aug. 5 in her home.
The child's identity has not been released.
SLED agents arrested Taylor at her home Thursday morning, according to SLED spokeswoman Jennifer Timmons. Calls to Timmons and the Department of Social Services were not returned Thursday evening.
Family members at Taylor's home said Thursday they did not wish to comment.
Neighbor Shirnell Bryant said Taylor has kept children at her Silver Bluff home for several years and she hadn't witnessed anything out of the ordinary when Taylor played with children outside.
Taylor is being held at the Aiken County Detention Center, awaiting her bond hearing.
