It seems every baby goes through a obsessed with keys phase. You don’t want them to put your keys in their mouths, but those plastic toy versions are no match for the real thing. Cue a smart momtrepreneur. Kleynimals are a stainless steel option…though you’ll have to find them in a brick and mortar store for now. Eli the Elephant, Gus the Giraffe, and Leo the Lion are non-toxic stainless steel “keys” that will satisfy baby’s desire to play with metal keys without the hazards of lead contamination, sharp edges, or the daily grime that come with the keys in the bottom of your diaper bag.
