They were heartbreaking moments as family members called for help while the grandmother tried to help save Trae-Lynn. Emergency responders arrived and transported him to an area hospital where he was pronounced dead.

"Trae-Lynn was the kind of baby who was joyful, knew he was loved, big eyes, smile," Coleman said.

Police said they have not discovered any signs of trauma. An autopsy has been planned, and no charges have been filed at this point.

As the family grieves over the death of the child who brought them so many smiles, they have a lot of questions.

"This day we were thinking about all the stuff he did that was so funny and what he loved," Coleman said. "That's how I want him to be remembered."
