Aha!!

Just read this in the take-home literature from the ped.  Would have been helpful to know this about a month ago...explains the high chair tantrums and pickiness :}

'You'll probably notice a sharp drop in your toddler's appetite after his first birthday.  Suddenly he's picky about what he eats, turns his head away after just a few bites, or resists coming to the table at mealtimes.  It may seem as if he should be eating more now that he's so active, but there's a good reason for the change.  His growth rate has slowed, and he really doesn't require as much food now.  Your toddler needs only about 1,000 calories a day to meet his needs for growth, energy, and good nutrition.'
