Actually one kid has been miserable, one has been picky, and the other is okay.
But let me tell you, the miserable one is taking all the fun out of food by complaining about everything that is available to eat in our house. He's subsisting on yogurt, graham crackers, and the mandatory "try-one-bite." Every time I think I've found something that he will eat, the next time it's offered he doesn't like it. About a year ago we drastically cut back on sugar in his diet and discovered that our very whiny child became even-keel. It's been great.
Except now it feels like he's fighting back.
It's no fun to expend the energy making food only to get it thrown back in your face with a big YUCK.
I think it's a 4 year-old phase. Right? Please tell me that your 4 year-old is or was picky, too.
