4. Don't hover over their shoulder- On the other hand, kids hate having an adult hanging over their shoulders scrutinizing and correcting their every move, and thus, it is very important to respect not only their personal space but their need to explore as they learn. So, rather than hover behind them like an overprotective parent, approach them to tell them or show them what you need to and then, back off and let them practice a bit while you provide a bit of friendly coaching from the sidelines.
5. Praise- Children are genetically preprogrammed to seek approval from both their peers and from adults who they either like or admire. Thus, by having patience with them, making fly fishing fun for them and, not hovering over their shoulder, while also praising their successes and pointing out but, not chastising, their mistakes, kids will appreciate you and thus, they will be far more inclined to listen to you and do as you instruct.
6. Remember that you are taller and stronger than they are- This is a big one! Adults tend to forget that they are both taller and stronger than kids are and thus, terrain that is relatively simple for an experienced adult to traverse can sometimes be extra challenging to a kid. So, when teaching kids to fly fish, it is important to remember that they are shorter, weaker, and lighter than you are and thus, it is important that you choose your path along the stream, as well as your stream crossings, with a kid's smaller stature in mind.
