Hi, what an interesting thread. I have four children, all brought up the same, same food etc, boundaries etc.
DS1 - Will not eat any fruit or any veg, except potatoes. Will not eat tomatoe based sauses etc. Likes white bread and butter. Will eat cereals and often eats 3 bowls for breakfast with full fat milk. Doesnt like cakes or chocolate much and wont eat crisps at all
DD1 & DD2 Twins- will eat absolutely anything, fruit, veg, wholegrains, pasta sauces etc. DD1 wont touch cake or choc but loves crips. dd2 loves, cakes choc, crisps, ice cream sweets
DS2 - IS nil by mouth
My point - children have their own likes and dislike and you can only guide them in the right direction, ultim ately, they grow and make their own decisions about food. As a by the by and probnot making much sense, ds1 who has never eaten fruit, veg or fish or wholegrain bread (or all the other stuff that helps brain functioning and concentration) has just left school with 11 gsces, 8 grade A*, 2 GRADE A and 1 grade B. So dont despair if your child wont eat totally healthy, organic food, you can only do your best and its not worth beating yourself up over.
