Satin would do that lick, lick, lick, CHOMP from time to time. Often, it was obvious: I'd used some lotion or whatnot. I'd have to hand her off (in a panic) to Hedgiedaddy while I washed and washed and washed because she could not be stopped. Lick, lick, lick, CHOMP! There were just some scents that, even though I couldn't smell them, *she* could. And it really sent her into an unstoppable frenzy.
When she was a baby, she did that to Hedgiedaddy every evening that he came home. I joked that he must have secretly worked in a meat-packing plant. I do miss those days - little hedgie girl... so small and so excited with HD came home. She did grow out of it. She used to anoint over his shoes... I don't suppose you work in the food industry?
Maybe it's a matter of finding the right soap to counter what you do during the day; eg, I needed to wash hands, arms, and belly with special chlorine-be-gone shampoo thoroughly after swimming in a pool, else she'd CHOMP.
Maybe it's a matter of your little one needing another month to figure the difference between you and food.
I am really happy to hear that the chomps are preceeded by licking. To me, that suggest he's curious and exploring rather than angry and aggressive.
For now, I think if I were in your situation, I'd get a small piece of fleece (washed in unscented detergent and no fabric softener or dryer sheet) and hold him in that. You'll have a layer of protection between you and his little teeth that's thin enough that your scent will pass through. You want him to get used to your scent.
The only other thing I can think of is that he's hungry - maybe his current food situation isn't working out for him. What kind of food does he normally have? And how much does he eat?
ETA: Garlic and cigarettes are two other things that seem to set them into a chomping frenzy - any possibility that's what's going on?
