First off, great photo Ryan!
We’ve taken our girls fishing since about the age of three.
We always had a bucket so they could play with minnows and leeches. When they’re that young they don’t know that leeches are “scary” They don’t mind handling them now, unlike my wife and brother in law.
We were lucky to have a small trailer on a lake in so fishing from a dock was doable. The boat got better with time but as mentioned snacks and toys were important.
We never stayed out long, about an hour to begin with and increased it as time went on. We would always try to wrap it up when the sunnies were biting very well, sometimes even making them a little bummed out. I think what they always remembered the most was how the trip ended. If we were having fun and catching fish they were excited to go again and the flipside was if they were crabby and whiny that’s what they associated fishing with.
It sure is enjoyable to see the excitement through their eyes. My girls are in their mid twenties now and just love being on the water and fishing. They do their own knot tying, make spinner rigs, bait hooks and clean fish. Can you hear the pride?
Be patient and have fun!
