She sounds completely normal to me as well. Emily can polish off 4 weetbix, 2 pieces of toast & some fruit, and that's just at brekkie! Emily doesn't like to eat when it's hot, so she eats most of her food in the morning/lunch, then hardly anything for afternoon tea/dinner. She's 15kg and sleeps 12 hours overnight, so I'm not complaining. Jazz would be letting you know if she's hungry.
