Hi, A.:
BINGO!
I have a 30 month old son who eats a fabulous breakfast and lunch, and largely refuses to eat any dinner. He's been doing this for several months, and at first I stressed about it, but then I realized that, overall, he's eating just fine and he regulates himself with food according to his own needs. He's growing normally and is very active, and since his other two meals are big, I've decided not to push it.
One note, however: I do NOT make him a separate meal from the rest of the family, although he would love for me to feed him "kid food" (primarily chicken nuggets) if I'd let him get away with it!! This is a line I don't want to cross, as I feel like its a negative example to set for both him and my other kids.
Best,
L.
