In addition to teaching them valuable skills, providing ownership also lets them experience the consequences of their actions, and important training tool for parents. If they behave themselves, and follow directions, they are rewarded dwith something that tastes good, and that will build their little ego's. If they misbehave, they suffer the consequences of not being allowed to assist, and maybe the treat they would have gotten if they had behaved.
I'ts a great teaching tool for parents. But remember, and this is important, to teach them to cleam up as they are cooking. It will avoid a great mess and much time. And they will learn to take pride in a clean kitchen.
