Folkmanis Mini Emperor Penguin Baby Finger Puppet Gray-blue, 1 EA

Q: What's the youngest child this is safe for?

I'm just your average customer, but I'd say 2+; there's no small parts, and it's not easy to rip pieces off. It's as safe as any other finger puppet; safer than most, even, since it's a pretty comfortable size. 2+ is my "just to be safe" guess at that. If supervised(on account of children being unusually wily at times), I'd let an infant chew on it, as long as it's clean, of course.
