Like Joanna K, they ate what we ate from day one.
Can you imagine trying to cook 10 different meals? I cannot.
I have seen kids that dictate to their parents what they will eat or not eat. Not a pretty picture!!! And tremendously disrespectful.
Occasional my older kids would tell my yourger kids that you won't like that. Besides correcting my older kids, I would tell my younger child, Oh Yeah, You won't like that. Its awful stuff. At the same time, I'm taking a bite of it and going uuuMMMM with a smile on my face. Then I would take another bite and tell them, Oh you don't want to eat this. Its awful stuff and I would take another bite and just smile and say uuummmmm! It worked very well about 90% of the time.
In our house, we've had awful stuff ice cream, cherry pie, french fries, fish sticks, milkshakes, broccoli with cheese sauce, trout, shrimp, tacos, enchiladas, fried chicken, steak. Just about anything I could think of. And upon occasion, the kids making the disparaging remarks had to eat the stuff they were telling the younger ones not to eat.
Good luck to you and yours.
