All children love to help in the kitchen and while that's not always possible, they can pretend play making their own creations whether with their parents in the kitchen or at their own kitchen pretend play set.
You can teach your children good habits in the kitchen by letting them put on their chef's outfit and letting them help with the meals. Teach your children to always wash their hands before working with food and talk to them about how germs make people sick and when your tell your kids about why cleanliness is so important in the kitchen area, they will understand and remember.
Never leave a child unattended in a kitchen when you are preparing a meal but you can let them stir a sauce with their wooden spoon, toss a salad, carry a warm (not hot!) plate of bread or rolls to the table using their baking mitt.
It's been proven in study after study that children learn best by doing hands on activities and retain that knowledge of what they learn. If your child longs to help you in the kitchen, find safe activities for them to do and let them wear a chef's outfit to add to the fun of the experience.
