My DS is 16 and is now able to explain much more why he eats as he does.
He is autistic and many of the food aversions are sensory. Eating something that he doesn’t like the taste/feel of is a really big deal for him, and so he is going to avoid that experience if possible. So he looks at his plate, and if he recognises everything then great, he eats it. But is he has had one negative experience with a food then he won’t eat it again. He has a narrow range of ‘safe’ foods that he trusts. He won’t eat sauces, mixed up foods (like spaghetti bolognaise) because he has no way of knowing what is in them.
He is happy to eat the same meals repeatedly.
When I was trying to extend his diet, meal times became a source of anxiety because he didn’t know what would be on his plate and that worried him. He was anxious about trying new things because if he doesn’t like them then that’s a really horrible experience for him. He says that he can still taste the food hours later.
And if at every meal someone is bothering him, trying to get him to eat more, try new things, finish up something he doesn’t like then he stops eating completely. He doesn’t want to come to meals because it’s too stressful.
He likes the same brands because he has tried them and he trusts them. Different brands can taste very different.
Life is different for fussy eaters, they don’t approach food in the same way that we do, it is a source of anxiety not enjoyment.
It is tricky, we can’t really eat out, although that’s not a treat for him anyway. I take a lunchbox and he will eat that. He goes out with his mates to fast food places but he doesn’t eat.
The things I have learned are:
From his perspective repetition and predictability are good - he doesn’t get bored.
The more anxious he is the less likely to be able to try new things, if he is too anxious he can’t eat at all.
If he is not anxious, he is more open to trying something new.
Things that look/taste the same to me are still very different to him.
If you trick them/try to ‘hide’ foods they won’t trust you.
He can tell if he won’t like something by smelling it.
If he does taste something then a bit of food the size of a grain of rice is enough.
He is not being naughty, controlling, or manipulative.
Odd combinations are okay, spaghetti, boiled egg and peas anyone?!
