I just posted this in May 2015 but could use the advice of the wiser crowd.
My LO cut his bottom front teeth a month ago and he's been chewing and sucking on everything since, including his own hands. This wasn't a problem until I started noticing little spots of blood on his sheets and figured out that he has actually bit his own wrist to the point of drawing blood.
Has anyone had this happen? Is this behavioral or just an accident? He does seem to do it when he's tired or about to fall asleep, but otherwise, during the day, he doesn't seem any more moody than usually.
