I was just wondering if anyone knows why kids do this? difficult child does this constantly with whatever is in her hands (toys, markers, wiimote etc). Lately it's been the neckline of her shirts and her sleeves. She chews on them to the point where they are soaked through? I often remind her to take stuff out of her mouth but it seems that she is totally unaware of what she's doing. I don't know any kids her age that do this??? Is there anything I can do to avoid it?
