i am having my annual fret about ds' eating habits. It's important to say that he is happy, healthy and thriving, but only eats a few core foods and won't/can't try anything new. Quantity is not the problem, it's variety, but what is really worrying me is how upset it makes him when we even broach the subject of a new taste.
He's 6, we've tried talking rationally about it (this works well for most things but not this), and we've tried rewards but even when it's something he desperately wants he'll get himself wound up into a state and won't try it and would rather not have the desired thing than try a new food. We try so hard not to put pressure on him, try to make it his choice to try something and there's a rule that if you don't like it you don't have to eat it, but his response to something new on his plate is getting worse and yesterday he asked to try something then got nearly hysterical when the moment came.
I'm concerned that it's turning into a phobia, and I don't know what to do.
Anyone have any advice? I'm desperate to help him as he is so disappointed in himself for not liking the same food as his friends 
Can the GP help? Is there a specialist that we could be referred to for this?
