My 14 month old adores my car keys, and I'm always concerned she puts them in here mouth, so I got her these Yummikeys after getting a teething necklace for my firstborn a few years ago. She adores them, they keep her distracted through nappy changes, she loves to bite them for teething, and I'm safe in the knowledge that I can dishwasher them to make sure they are clean and healthy for her to play with. And I've got my car keys back! Win win.
