My 9-month-old son has started teething (well, he's onto his 5th tooth) and as a result he is biting - whether it be the table, toys or fingers. The issue is he was never one for a dummy, and from a young age he would simply suck on your finger to fall asleep - trust me, it wasn't to my satisfaction needing to have my thumb sucked!
So going forward, naturally he thinks that it's okay to put our fingers in his mouth and to bite - yikes! I do not want to yell/punish him because, well, not only is it self-inflicted, he is far too young to understand what he is doing is wrong. Of course, we usher "no" and try to demonstrate this is not acceptable behavior, but at the same time, we do not think it is making a difference.
We've tried dummies, rings and other toys and whilst he does play with them (albeit short) it doesn't stop him from trying to bite me.
What method(s) can we use to demonstrate that what he is doing is wrong, without "punishment" (as in, growling or raising/changing our voice) for our son?
