My DD is exactly the same, you could have been writing about her! Brekky is a bowl of porridge, a peice of toast and a banana, morning tea she gets fruit, lunch is what every 1 have, and the same amount! afternoon snack more fruit or steamed veg, and dinner is whatever i have. and thats not counting everything in between!!! Sultanas is a good one to keep her busy for about half hour, she eats them one by one, or a cruskit, fruit, arrowroot biscuits, those hinze bars, she always is eating something! she is about 11kg, dunno how tall tho...

Sounds very similar to your little man
