My 5 year old has such an aversion to food sometimes. He eats the same 5/6 meals (which is honestly fine but gets boring for the rest of us having to have those meals). I try a few times a month to get him to try something new but he despises the texture of things. He literally spits things out because he can’t stand it that much. He says he hates the way things feel on his tongue eg rice, watermelon, strawberries, his bananas have to be a certain amount of ripeness or he won’t even entertain them
He is also quite funny about “germs”, he doesn’t like me to kiss his lips specifically (which, again, is fine and I would never do it if he didn’t want me to) or sometimes even any of his face because “we don’t have the same germs” and I notice when others hug him it’s like he things it’s gross.
I can see him visibly cringe when it’s time to brush his teeth and he really doesn’t want to put the toothbrush in his mouth
I’m sure there are more examples if I were to think hard enough but how normal is this behaviour?
