Fruit nibblers can be an excellent tool for teething, especially when molars are coming in and standard teethers aren't reaching the right spots. You can place chunks of frozen fruit or fruit puree inside the silicone sac to provide cooling, soothing relief for tender gums. Look for nibblers with a 'rotary propulsion' design, which helps push the fruit up as the baby eats, preventing frustration and ensuring they can reach the contents easily.
