I've been trying to wean him off the bottle and on to a cup for several weeks now - absolutely no interest whatsoever. We offer a cup of milk at morning milky time (not a bottle), he doesn't want to know. So please don't tell me he shouldn't still be on bottles... I know 
But my more immediate problem is that he's now started choking on his bottles too. Every few seconds, he splutters about like a loon. He had a terrible teething weekend but is now back to normal - could that be why? Starting to wonder if he will ever drink properly...
