I agree, it's an excellent idea to involve toddlers in the kitchen! Using age-appropriate utensils and ingredients, toddlers can practice their grasp on sensory play and hand-eye coordination.
Some fun activities which introduce toddlers to new foods could include having them grow their herb gardens indoors; it teaches them about the source of food and encourages an appreciation for nature too!
Another activity could be creating a 'taste bud adventure' with various healthy foods covered up, where they guess the flavors and textures - even blindfolding them adds to the fun and excitement. You could also incorporate a creative aspect by having them decorate healthy cookies or pizzas, which enticingly introduces new flavors in a familiar context.
Making meals into a sensory experience with different textures and colors is a great way to spark their curiosity about food and its origins. It's a great first step to fostering positive relationships with food and nutrition!
