The step-by-step teethers are safe, ergonomic, light and really fun. The rubber teether is indicated for incisors and is therefore suitable for babies from 0 months. The little rubber bubbles massage the gums and it is very lightweight. The chilled teether is indicated to first molars and babies over 4 months. By cooling the distilled water it contains, it alleviates inflamed gums, as well as strengthening the teeth thanks to its different textures.
