I've noticed that some of my friends' children really don't seem to care when (or if) they eat. My nieces and nephew never seem to be interested in eating; something else more interesting is always going on. I can see how this might be frustrating, since we know we need to get some nutrition in our kids.
But then there are kids like ours. Oh my. The moment their eyes open in the morning, they are asking for breakfast. Lucy walks around saying, "Cheese? Cheese?! Cheese!" Nate wants to know if it's time for pancakes yet. Not very long after they eat a very full breakfast, they start asking questions about when lunch is. On weekends, Lucy eats her large breakfast (example: 3 Trader Joe's pancakes, 2 cheese sticks, half a banana), then 20 minutes later she's trying to charm Jon into giving her some of his. (She kisses and hugs his leg and makes puppy dog eyes at him.)
The worst hour of the day is the hour before their dinner time. They follow me around, asking for food, when's dinner ready? what time is dinner tonight? what are you going to make? pulling on my leg. It's getting a bit better, but some days I wish our kitchen had a door so I could lock the children out while I get their food ready!
I really don't think the issue is whether or not I feed them enough; they eat a ton and also get a morning snack and afternoon snack.
So I guess it's hard no matter which way your kids are: if they are not interested in food at all, you struggle during meal time to get them to actually eat (but the rest of the day is easier); if they are food lovers (e.g., Nate & Lucy), meal time is great because they're happy and they eat like little piggies (but the rest of the day can be torture if they're always asking for food). How are your kids?
