Teething can be a trying time for babies. They usually spend this time putting things in their mouth to relieve the itching. Therefore, a specially designed teether can be an important tool to comfort your baby. Water-filled teethers, especially those that can be cooled in a refrigerator, work by gently massaging the gums. It’s best they’re filled with drinking water and made from safe materials. You can even choose eye-catching colorful and bright soothers.
