He is 3 and has always chewed the top of his coat. No idea why.
In the past two days he has started chewing everything that's in his hands. Two rolled up posters, a corner of a book, a foam sword, polystyrene which he took bites out of and his fingers.
I tell him to stop and he will but the object will find its way back in to his mouth. Anyone have any idea why? Its only jus come on suddenly.
