at the minute Sheldon is 10 months old and over the last few weeks has started chewing things. In the past hes chewed string and elastic from his toys but now he's chewing anythin he can get his hands on from tapemeasures to ornaments to my shoes jst anythin. i've had a look at his teeth and there seems to be nothing wrong and hes still eating.
Does anyone have any ideas why this may be?

thanx in advance for replies
