We've been doing all kinds of tricks to get our son to eat more, and to eat healthy foods. Since he's preschool-age and learning his letters, these have been perfect! I cut deli meats, cheeses, bell peppers, melon, etc., for his meals. Sometimes I spell out a word or his name, or sometimes I just put in a few letters. I've even been able to coordinate the 'letter of the week' with his preschool teacher. We had fun putting everyone's initials in crust on the top of personal pot pies.
One tip - since they're small, have a few toothpicks handy to poke the food back out after cutting it! Depending on the food, it can stick. Take care of these - wash and then dry well. I usually put the dry cutters on a small cookie sheet in my toaster oven and turn it on warm. This gets them completely dry and prevents rusting!
