I definitely am keeping the button rod just for how much fun he had with it in the boat
You can be trolling or bobber fishing with another rod (make sure he knows that one is his to watch) and using his snoopy rod with the green fish at the same time because there is no hook on the line of the snoppy rod. I don’t think a CO will get you for using multiple lines. Anything you can think of to just spend more time on the water with them. I have even tied a hula hoop to the back of the boat and had him try to cast into it. He can pop a plain weight right out and try again.
