More food please!

I am well aware that with 3 boys, I will eventually have to mortgage my house to keep up with the ever growing grocery bill.
I know that when they hit 11, 12, or so, that boys tend to suddenly need 12 meals a day, plus snacks. I remember my brother at that pre-teen/teenager stage when he would come home from school, eat a whole box of Macaroni and cheese, and STILL eat a full dinner - with dessert!
Multiply that by 3 and you see why I am saving up now, for 10 years down the road when I have to restock my cupboards and refrigerator on a daily basis. I should buy stock in Kraft Dinner and Pizza Pockets now, maybe I can make some money to offset the cost of their hollow legs.
Chris and I thought it was bad now - buying milk every other day (seriously, these boys can put away 2 litres a day easily **that's half a gallon)

Which brings me to the point of this rambling post - growing boys eat a lot.

Today, after I dropped the older boys off at school, I took the baby out shopping and arrived home just in time to hear the phone ringing.
It was the secretary from Duncan's school - I've gotten to know her quite well, and will get to know her much better over the course of the next few years I'm sure.
She greeted me with "Hello, Duncan is fine............BUT..........."

This was her way of alleviating my worry, right from the start - Oh phew, my son is fine - than she throws a big "BUT" in there.

Now as a mother, my brain can work in overtime when it comes to my kids - before she could finish her sentence, a thousand and two possible scenarios have already gone through my head.
Eg. He's fine - BUT, he's running around naked and won't put his clothes back on.
or He's fine - BUT, he'll have a wicked headache from that gooseegg on his noggin
or He's fine - BUT, his head is stuck in chair and they've called emergency people to saw it off
or He's fine - BUT, he's locked in the bathroom screaming his head off

you get the idea.

I simply wasn't prepared for:
"He's fine - but he has nothing to eat for lunch"

This is phone worthy? Hello - check his lunchbox - I packed PLENTY, including 2 snacks for morning and afternoon.

Seems my hungry little boy, in addition to the large waffle breakfast he had this morning, ate both snacks AND his whole lunch at morning snack time, leaving nothing for the rest of the day.

so off I go racing to the school - with new lunch in hand, as well as an additional afternoon snack. I guess he's hit a growth spurt - or else he'll eat nothing for the rest of the day (Highly possible - kids have funny food schedules sometimes)

Anyway, he's only 4 - I was hoping I had a few years left before I had to sell off our worldly possessions to keep them well fed. ;)
