Also I was chatting to my mum about it, and asking her if she worried much about my eating then, and she said a little but not that much, we are not a family of worriers but she said mainly it was because there wasn't all this information about having to eat this and that and external pressures about varied diets etc, and her diet had not been that varied as a child and she had turned out ok, so she didn't worry much she said it did bother her a little but in the end she just went with it.

I think there is actually so much focus on what to eat and what not to eat these days and children have lived on quite limited diets in the recent past with far more limited diets than many fussy eaters do now. (Recently I think in UK was a girl who only ate chocolate for about 5 years, they did some tests on her and she wasn't actually deficient in any of the main vitamins/minerals - which I find amazing but the body is a clever thing and I reckon as long as you are getting some not highly processed foods into it, will be ok unless showing other signs of problems which might be caused by diet).

I suppose I try to look at these things in terms of what is the root problem trying to solve? So if the problem was say iron deficiency then look at ways to increase it within the foods that will be eaten, but I am not convinced that a non-varied diet is a problem in itself - IYKWIM.
