my 10 month old ds's kisses (sucking your face!) have now turned into biting since he now has 6 teeth. Which doesn't bother me, but he has started doing it to other babies at playgroup. I realise that he has the urge to bite on something as he is teething, but would prefer it not to be another child! Should I be telling him 'no' to teach him that biting is wrong or should I just try and intercept him before it happens? I am worried that he just wont understand what he's done wrong as it is a natural urge for him not an aggressive thing and I have been told that you shouldn't say no to them at this age as it can affect their confidence. Any advice on how to handle this would be really appreciated!
