You find kids at >12mnths still eating finely blended food. Introduction of solids is often between 4-6mo. Starting w finely blended foods.
Kids need to start eating more texturized foods frm 7-9mo. After this, it can be difficult as they have developed habit of not chewing.
This over blending can be due to many reasons.
I see the “parenting by fear” trend that is telling parents kids will choke on food.
Or maybe it’s just trendy to say I bought blender “xyz”;
Or that “you know my baby is so fussy/ is a lazy chewer”
