Chinuch Hora'ah of the Day:
Regarding a child who exhibits mischievous behavior [שובב], this is quite normal, especially for a firstborn son. Hence, there is no reason to be alarmed. As for how to improve that which needs improvement in this area, consult with educators who are experienced with this, and they should instruct you based on their experience.
