What is the supplication that helps alleviate nervousness when dealing with children?

The Prophet, peace and blessings be upon him, used to ask Allah Almighty for good character. Among what has been reported from him concerning this is: "O Allah, just as You have made my physical form good, so too make my character good," and his supplication: "Guide me to the best of characters, for none guides to the best of them except You, and turn away from me the evil of them, for none turns away from the evil of them except You," and "O Allah, I seek refuge in You from dissension, hypocrisy, and bad manners." It is recommended to adhere to these supplications and to recite them frequently to seek improvement in character, patience, forbearance, and the ability to suppress anger.
