Hatfield recommends that hatchlings and young juvies be fed twice a day and that they should be able to clean their plate at both feedings. My vet knows some herpers who underfeed their igs on purpose... enough to keep them healthy, but not enough to make them grow too fast.
I still feed Xander twice a day. I give him a heap in the morning and let him work on it until early afternoon, then I replace it with a small helping of fresh greens and let him finish what he wants. So I guess I go by everyone else's advice: let him eat as much as he wants.
