This is the only time in their entire lives that the food service industry will look like fun. Let 'em play.
Tell a thirteen year old they've got to make sandwiches all summer, and what will you hear? MOM! DAD! NOOOOOO! Tell a nineteen year old they've got to make pizzas all summer and what will they say? MAN, I WANTED TO DO STUFF WITH MY BUDS! Tell your three year old you bought them some Melissa & Doug play food and they'll say thank you- IF they aren't too busy opening the box.
And why is this? Well, that's simple. A teenager sees making food as a chore, an obstacle, something standing between them and their goal of doing whatever they want. A pre-schooler, though? They aren't allowed to turn on the oven and open the fridge and use the pizza cutter! So of COURSE it's exciting to them! And it's safe, too, because Melissa & Doug know what they're doing in the toy workshop.
Just be aware, ordering a kid-sized deep fat fryer is both unsafe AND unhealthy.
