Fifty-year-old John Pecot is charged.
Police records say in November, the alleged victim made an outcry stating Pecot touched her multiple times.
Authorities say they spoke with Pecot, who said he helped the girl's mother care for her.
He said he would bathe the victim and that he may have touched her, but if he did, it would have been "inadvertently."
Pecot also told investigators the five-year-old asked him to touch her.
Authorities say he was arrested because a victim that age wouldn't know the details she described unless she saw or experienced the assault.
