There are no standard sizing guidelines for children’s jewelry. Like adults, babies come in all shapes and sizes, regardless of their age. Please, measure your child and choose the right fit. Each piece is created with room to grow. Baby Emi Jewelry Jingle Bell Bracelet and Jingle Bell Anklet are adjustable by securing the clasp along the Rolo chain for a custom fit. Our Name Bracelets include a Sterling Silver Chain Extender to allow room to grow, just fasten the clasp along the extender for additional length.
