Normal??

Is it normal for a 17 month old to eat three eggs, a container of yogurt, pineapple, green beans, and graham crackers for breakfast and still be hungry? Or does my boy just have a bottomless belly??

P.S. Does anyone know if there's a limit on how many eggs a kid can have a day? Since he couldn't even have egg whites until 12 months because of the amount of protein in them, I can't help but wonder. I told the nurse yesterday when I called to find out that he would easily eat half a dozen eggs a day. When she asks how often he eats three eggs a day, I told her everyday (now that I think about it though, a lot of days I only let him have two, but still!). Yep, my boy LOVES his eggs :)

UPDATE: I just heard back from the doctor, and the recommendation is 6-9 per WEEK. Poor little boy :(
