Police are making enquiries in order to speak to a father who left his Skegness home with his 20-month-old daughter.
Officers say they currently have no concerns about the child's safety.
It comes after photos and messages about a young girl were shared across a number of Facebook pages and social media in the Skegness area.
A Lincolnshire Police spokesperson said: "We are not making a public appeal for assistance and there are no current concerns for the child's safety.
"We believe this enquiry is the source of Facebook conversation about a missing three-year-old."
