Thanks for your reply. I guess this would fall under different families tolerating things differently... I understand that he is only 2.5 and that he needs to experiment and learn about the world. However, it needs to be in an appropriate way. I do not consider shredding your food till it is inedible and throwing it across the kitchen an appropriate way to experiment with textures- even for a 2.5 yo. That's for the sandbox, play dough, the bath, "helping" mommy cook, playing with the fallen leaves outside etc. "Re-channeling the need to play in an acceptable way," as you mentioned. I do not expect him to eat perfectly like an adult. I do look away from what I believe is age appropriate experimenting and/or the kind of behaviors that will pass. For example, licking the cover of his yogurt when he opens it, opening up his sandwich before eating it, rolling his turkey up and eating it like that etc.
I try to "start as I mean to go on." Food is for eating, not for playing and wasting. We eat politely at the table. And yes, I have seen older children with bad table manners. I am trying to go about teaching manners in a light way that will not cause negative associations and make things worse/ make him more picky.
I don't mean to attack, I just feel very strongly about this.
