My son is not even 2 yet but that photo makes me look forward to fishing with him (if he likes to fish).
My grandson is 2 and a half and he is hooked !!!!
Last weekend he was down and Mimi asked him if he would like to watch a cartoon and he said fishing show , fishing show.
I'm sure your son will be the same, you are going to love the time spent with him.
One warning, they grow up FAST
