Zane is either:
a) teething again (still)
b) preparing to cover himself in a cocoon of ectoplasmic goo so as to emerge a fully-toothed young boy at a later date
Yesterday Zane was literally covered in goo: it was coming out of his nose, he was drooling, as well as shoving both hands in his mouth to extract it manually. And since he hasn’t learned the fine art of using his sleeve I had to use mine and am thus slimed by association. Serious slime goo boy.
While I didn’t get photographic evidence, there were a few moments right after wiping off goo that I gained enough purchase to peel up a lip and look for teeth. There’s serious angry red gum tooth outlines, but nothing has breached.
