My 10 month old DS keeps biting - sometimes because I've put my finger in his mouth to remove something he's put in there ( at the moment everything is going in the mouth), but sometimes he'll give you a good bite, just for the 'fun' of it.
He's got nearly 6 teeth and it bloody hurts - what's the best way to get him to stop? A firm NO is often met with a 'cheeky' smile/laugh and I'd like to nip it in the bud before he goes to nursery.
