@CardiBSlays It's all she knows of him and likely only thinks to call him that since she probably doesn't know his name. She may not even understand the significance of the term "Daddy" other than he fathered her. To her, he is Daddy the same way the moon is Mr Moon.
Ive been staring at the ''child'' for so long and feeling so sad coz im seeing how thin and small she is....... hope SHE GETS BETTER AND LOVED in the next chapters
