Where's the sanitizer?

Well, Bean is 12 weeks old today, and we've hit the stage where everything goes into his mouth! Hands, our fingers, toys, whatever he can grab! His new thing is grabbing my hand and trying to put my fingers in his mouth during diaper changes on the changing table. Doesn't make diaper changes easy! We now have to clean his hands more along with other things that go in his mouth. We also started introducing teething rings because he has begun chewing on said hands, not just sucking on them, and he's such a drool machine now! Teething starting maybe?
Here's how we spent this morning's diaper change:

He's growing so fast!
