Absent, I hear you on the unimportant decision front, but what happens when the answer to fish fingers or (cant remember other option) is chocolate? And if you give in to this, what if it is every day?
I remember when my eldest was young, I fell into the food trap for a while. My mother had always said i had to taste things, but didnt have to eat what i didnt like. This worked well with me, but then I loved eating - still do. With my daughter it meant that one day when she was about four, i realised that she only wanted sausages chips and eggs! We then decided that rules had to change and she had to eat what was on her plate - it took a long time to get her to understand the change and tears were plentiful (for both of us) Lesson learned. My two younger ones always had to eat what was on their plate, and will now eat pretty much whatever is served, with few exceptions.
We are bringing up people (who will one day be adults and have to adapt to society), not little kings and queens. If we consent their every whim when they are young, what will happen when they find they cant have their own way ALL THE TIME?
