Getting young kids to eat can be a challenge. When they dawdle over their food, you may find your urgings to eat have little effect.
Try a different approach. Tap into their imagination. Based on what they like, consider renaming your food. I met a Wisconsin mother who serves peas mixed with corn and calls them "Packer Veggies", because that's the colors of the Green Bay Packers. Her kids gobble down the peas and corn.
I met an Illinois mom who got her daughter to eat a pulled pork sandwich simply by asking, "Do you want a Dora (The Explorer) sandwich?"
What TV shows, books, and movies do your kids like? Try renaming a food item to put in in synch with your preschooler's preferences. Bon appetit.
