'Given that he had numerous issues with taste of food, this wasn't a control issue.'
OK can I just clarify that I was responding to YOUR example when you said 'At one point ds wouldn't eat a biscuit if it was the 'wrong shape'. '
Maybe you're right that refusing to eat a biscuit because it is the wrong shape (when shape has nothing to do with taste) has nothing to do with control. I'll just leave that hanging...
Which is, rather, the point that a few people have been making.
'you may have had the good fortune to have children who accept a range of foods(as I was with dd)'
I think you're rather missing my point. My kids were not BORN willing to eat a range of foods any more than they were born being able to read or brush their teeth or cross the road. It is something we have worked on by eating together and providing role models for example, by encouraging attempts at trying new food and ignoring food refusal etc etc. There are some foods which they still don't like which is the case for most normal people. Not liking the odd food stuff is not the same thing as refusing all vegetables or brown bread or anything which is brown in colour which is not normal at least not if it's a long-term state of affairs and not healthy (this is not my opinion this is a nutritional fact).
'You cannot assume that all children who do not are the result of poor, or over neurotic parenting.'
I am not saying this I'm just saying that when a child is a fussy eater (which is not I repeat the same as not liking everything they ever encounter) it is very often the result of the parents handling or not of food with the child. Again, this is hardly ground breaking stuff. It's really just common sense and backed up by research.
Take Tanya Byron (a clinical psychologist with an expertise in issues to do with children and eating) for example in the House of Tiny Tearaways book,
'at the root of almost every child's eating pormlem that I have experienced is an anxious parent; and often an anxious parent who is also obsesively clean and tidy'
