The arrival of teeth comes with many benefits and drawbacks. On the plus side, eating is an obvious benefit. With teeth, he can suddenly access larger chunks of food and it's quite an impressive feat watching him eat a banana in ever increasing bite sizes.
Molars also mean that he's able to chew his food a little more, meaning that we can be a bit more adventurous with what we're feeding him. He's now able to manage chunks in his food as well as harder biscuits and bars.
On the flip side, cute games such as "gum on daddy's nose" are now no longer viable, and teeth marks are slowly appearing on the pages of his favourite books. The biggest problem, for me at least, is that sometimes when he's in a cuddly mood, he likes to curl up and nuzzle into my shoulder. On a couple of occasions recently, this nuzzle has turned into a bite (surprisingly painful!) and it's a tough situation trying to convey what "no" means to Jake. I've gone for saying no, frowning at him and moving him away from my shoulder to do something else, but whether this will work in the long term waits to be seen. I know that little kids use their teeth occasionally, but I'd rather not be called from nursery about Jake biting someone, so for now I'll be trying to encourage him to use his teeth for good rather than evil.
