My kids are both ends, my 15 year old son wants nothing to do with fishing. He is out for 15-20 minutes on the boat and the the pole get set down and he is eating or texting or trying to sleep. My 10 year old daughter on the other hand. I get her set up with something she wants to use. She has things she likes to use, sometimes frogs, sometimes jerkbaits etc..... and she will literally fish for 8 hours. Bring her a little food and drink and she is set. My 4 year old loves to fish, as long as it is blue gills and he is reeling them in one after another. Once they slow down, he is looking for rocks to throw, food to eat, lol. I just try to let them do their own thing. If I try to force, they go the opposite direction. They don't have to fish, just spending time with them is more than most get. Bring them along and compromise, let them bring their cell or little handheld games or books whatever.
