Cooking is empowering to kids! The very idea that your little one gets to use fuel and an igniting system; and then start a fire are highlights for many trips! For my kids, the very thought of “being in charge of a meal” gives them a sense of self-worth because they are contributing to the effort and being entrusted with fire and boiling water/food. When I asked my daughter what she liked most about getting to cook a meal while camping she said, “It is so much fun setting it up and starting the flame. I also like dishing out the food to everyone.”
I started talking my kids through the process of cooking when they were about 5 or 6. Currently we use butane fuel with a stove that has an igniter switch. We started with ensuring, there was water in the pot before igniting the flame and moved on to how to properly melt snow in a pot. We walked them through the importance of stove placement selection in regards to terrain and weather and how to start the stove if the igniter switch gets melted due to improper use (think blow torch to start camp fire gone wrong).
I encourage you to get your little one involved in some process of cooking if they are ready. It may bring an additional appreciation for camping.
