Did you start laughing the moment you read the title of this blog post? It's not funny.
It's not funny when your son is either so impressed or pained by his new teeth that he bites anything within an inch of his mouth. The spoon or finger you are feeding him with. The fleshy part of your thigh as he pulls up on your leg. The arm of another child who happened to reach past Milo's face (this generated an "incident report" at school). After he bites you/something, he grins as though to say "The world is so DELICIOUS."
It's not funny.
