Give your kid a moderate amount of junk food. You don't want her to be the fattest kid in the 4th grade, but you don't want her to be the annoying neighbor kid who steals everyone's candy and sugar cereal, either.
We probably all have personal experiences relating to that. I think i was on the deprivation end and loved going to friends' houses who had all the great ice cream and candy. I think one friend had Goofy popsicles--hello.
