Wow we've come a long way since then... DD1 (7) now not only catches her own fish but she can cast her rod, identify the fish (those we know and catch often) and holds them.
She's asked to learn to bait her own hook since she was about 4 but we are still cautious on that front.
DD2 loves fishing but can barely sit still, she is more than happy to run around and then just take her rid when a fish is hooked.
Even with a broken arm she caught a 33cm flathead last weekend!
