My daughter is a typical 6yr old. Enjoys fishing for all of an hour - which I am happy to oblige to. Like most young children, the act of not "catching" anything really turns them off. Because of this, our main spot is the pond at our house - loaded with BG and Perch, and we can catch a dozen or two in that hour all while having just a blast of a time.
While I have hopes that she will grow to have a passion for bass fishing, as this can set the foundation of an even more fruitful relationship with her throughout time, I cannot force that upon her. In time, as she grows, decisions and passions will be made and created.
All I can do now is enjoy the time spent at the pond, make memories, and ensure she's having fun!
