My kids love to help in the kitchen. It's not always easy so I try to come up with things that they can do "on their own" and doesn't require a lot of ingredients or clean-up. We made homemade whipped cream that they used as the filling for their own personal strawberry shortcakes!
My son said, "Mommy! I have a great idea! You can teach me how to cook like you and I can teach 'Evelyn' & 'Janelle'!" I chuckled and said ok! He calls himself the head chef!
