I do this all the time. I like the smaller portions; they are just the right amount of food. Regular sized meals are often too much for me and biggie sized is just plain gluttonous (unless I haven't eaten all day, in which case my stomach still isn't better equipped to handle all that food, but I'll feel better about eating it.) I just get a "boy" toy so that they have a harder time telling it's for me. I eat the food, give the toy to my nephew, and call it a day.
