Lakewood Police arrested 23-year-old Adam Laham on Friday after the child was shot inside an apartment. The boy was taken to the hospital where he later died. His name was not released.
Laham had an advisement hearing on Saturday morning where his bond was set at $40,000.
He is facing charges of child abuse resulting in death and criminal negligence.
It's believed Laham was a family friend from Kansas who was watching the children. Police believe he is not related to either child.
Police have not released details about the shooting and say all warrants and court documents have been sealed.
Police would say that other people were at the apartment at the time of the shooting.
Laham is set to appear in court again on Dec. 30.
