Why was the son in the Tarkhad family initially so reluctant to travel to Shirdi, and what changed his mind?

The son was deeply devoted to his daily worship of Sai Baba's photograph, which included the crucial ritual of offering 'Naivedya' (food offering). As detailed in Chapter 9, his primary worry was, "Who will perform the worship at home regularly?" He was especially concerned because his father followed the Prarthana Samaj, which made him question if his father could properly handle idol worship. He only agreed to go to Shirdi with his mother after he received a firm assurance from his father. Babasaheb Tarkhad promised that he would personally perform the Naivedya offering every day and that no one in the house would eat until the offering was made to Sai, which finally put the son's mind at ease for the journey.
