It is a southern thing..back in the day, i rememebr my neighbor had her child in the casket at her home. She was from the south, but don't recall where. she had pictures of deceased relatives in a album.
i would not do it myself, but i think taking a picture is a personal thing. maybe she posted is on FB for relatives and friends..who knows.
it would take a whole lot more than that, for me to worry about my daughter living with one of thier family members..
JMHO
