Hello TheAdventuresofBarnaby
our 9 month old, Mason, stopped biting, as you say, at about 6 months, but a month or so later started mouthing affectionately. He doesn't come close to hurting, just gently holds you fingers with his teeth. We hadn't thought to discourage him, it's quite nice, but something I read on CoL a few days ago made me think that he might hurt somebody and so we've started training him to not bite. It's a shame - he has so few ways of communicating - but just in case...
