Just like adults, not all kids are hungry first thing in the morning. I have friends that wont eat for 2 hours after being up and others that have to eat right away. My own kids are like that... my daughter wants to eat the second she is up, my son likes to wait an hour or so (longer on weekends) so... I say let em. They will let you know when they are hungry and if that means waiting til morning snack... whatever.
