Encouraging my sister to wash her hands is challenging. Firstly,she don't fully understand the importance of hand hygiene inpreventing illnesses. Secondly,she find the task boring or unnecessary, especially if she don't see immediate consequences of not washing her hands. She resist handwashing due to a desire for independence or simply because she find the process tedious. Overcoming these challenges often requires patience, consistency, and creative approaches to make handwashing fun and engaging.
