James Michael Williams is charged with felony child neglect creating the risk of injury.
A criminal complaint accuses Williams of putting Natural Ice Light beer into the 11-month-old's bottle on Friday.
Police were unable to determine if the child drank any beer. The baby's mother and Williams' cousin, Ebony Williams, said her child vomited shortly after she took the bottle away.
Williams told police her cousin said he did it as a practical joke, but didn't allow the child to consume any beer.
James Williams has not yet secured an attorney and no phone listing could be found for him.
