Sephiroth likes kids but is incompetent at dealing with them.
His kid would ask him to read a book to them before bed. Sephiroth would read a dictionary to them, or a textbook on neuroscience. At least the kid doesn't mind. They just wanted to be soothed to sleep by his voice.
He would either be very stringent about fulfilling their needs or never be able to deny the child anything.
