I think Rhys has told his first pun.
For the last few weeks, he has been nursing on my nose. I'll hold him up to my face, and he'll grin a big grin and glomp onto my nose, for a few seconds, and then grinning even more and giggling. I'll wipe my nose on his belly, and he'll guffaw (and more than when I nose-tickle his belly without the nose-nursing.)
He knows it's not nursing, I'm convinced. And he's not teething on my nose the way he teethes on everything else around. So ... it's a pun. A baby-style pun.
I may be anthropomorphizing ... um ... he is anthropomorphic already ... adulterating ... adulterizing ... I dunno what the right word is. Attributing adultness to a baby. But I think he means it as a pun.
