Constantly Hungry

I’m trying to figure out if it’s boredom, a habit, or real. Anyone else’s boy constantly asking for more food/drink? Anything I give him he asks for more.

We’re homeschooling and he just learned ordinal numbers. So now he’s like “Can I have a second banana? Can I have a third slice of pizza?” He has always been a good eater. So part of me feels bad that I’m not feeding him enough.

His older sister struggles to this day with it and doesn’t need much to be satisfied. Even her favorite foods she’s ok with just a little.
