We eat 5-6 small meals a day (as recommended by nutritionists) instead of a couple of "big" meals. Essentially we eat every 3 hours.
Ex) times being fairly flexible:
7 - cereal (or dinner leftovers)
10 - brunch (eggs, crepes, omlettes, etc)
1 - sammies (hot or cold), or soup, or salads, or sushi, or, or, or...
4 - 'tea'
7 - dinner
9 - hot chocolate (whole milk) and a bananna (for the K+ to avoid muscle cramps from growing pains)
midnight - during growth spurts (dinner reheated & whole milk hot chocolate)
HOWEVER, we eat about as "much" as if we only ate 3 meals a day (less for the adults, more like 2 meals a day... because we're not overeating from being overhungry. Kids naturally self regulate except with certain kinds of food, adults overeat when there are large gaps between meals). It's just spaced out. When kiddo is really active, like the winter when playing in the snow, or summer swimming, we eat every hour. I only cook 3 times a day (brunch, lunch, and dinner... but we hold over leftovers from each meal for the in between one, and have lots of easy access food - like bagels and lox, or yogurt and granola, or cucumber sammies, or sushi, or deviled eggs... things that are already prepared, like leftovers, and just need to be taken out.
From a nutritional standpoint it's better for both kids and adults not to starve and gorge. But for kids, eating right before bed helps them sleep through the night. Many kids, however, go through periods of eating like birds during certain phases. When kiddo's hungry, he eats. When he's not, he doesn't. It's pretty simple and amazingly healthy to watch how his body naturally knows what it needs when. As an adult I've had to relearn how to eat healthily from YEARS of being unhealthy in my eating habits. But I can tell EXACTLY where he is in his growth cycles by watching how much he eats. I always give him adult portions, and he eats until he's full. Then the leftovers go on his shelf in the fridge, and he can have them whenever. Right before growing he eats ALL of the portion I give him, and will ask for more. During a growth spurt he'll only eat a few bites at every meal. Most of the time, however, he eats about half. It's been really fun to watch over the past 8 years just "feeding on demand" how apparently humans are born knowing when and how much to eat... it's just that our parents have trained us out of listening to our bodies.
