Just as soon as baby stole the key to your heart, she was angling for the set to your car.

Hand over Kleynimals instead, the new stainless steel animal-shaped teether, er, keys for gumming babies.

The jingly-jangly ring comes with keys resembling an elephant, giraffe, and lion. Instead of the sharp, germy, lead-filled keys you put into your ignition, your little locksmith will get a nontoxic, ecofriendly, and equally satisfying food-grade stainless steel that’s safe for her mouth.

Plus, they can be tossed in the dishwasher. Would we steer you wrong?

Available online at kleynimals.com, $24.
