His teeth are brushed at least twice a day - and ive had a good look at them for debris, but nothing - but since yesterday, good lord. The smell is bad enough to make me recoil, and I'm his mum so supposed to love everything about him. But this is something else. It's like there's something in his spit as well because he licked my face (he is 3) and now my face smells awful as well.
Short of eating poo, which I'm sure he hasn't done, what on earth could be causing this horrible smell? And how do we stop it?
