How can I teach an orally-fixated, teething, 9 month old that biting isn’t fun? I’ve tried modeling better behavior by caressing him softly while saying “gentle,” offering a variety of colorful, cool teething toys instead, putting him down immediately after he chomps me with a quick and direct “no biting” phrase, making a disappointed face, and, of course, when he catches me off guard, involuntarily shouting “ouch!” — which doesn’t seem to deter him, either. Instead, he often smiles and sometimes even laughs afterwards. Clearly, he thinks he’s playing games, regardless of my reaction. Those tiny, precious teeth — two growing nubs and four sweet-looking chicklets — don’t feel so darling!
