Teethers designed to be pre-chilled offer extra comfort to swollen gums. But don't put teethers in the freezer. Frozen surfaces can hurt a baby's tender gums. 2. The best way to relieve teething pressure is with counter-pressure. That's why teething babies love to chew and bite on just about everything! 3. For most babies, the first tooth appears sometime between six and nine months. However, heredity is the determining factor, so parents who got their teeth early can expect to see teeth sooner, perhaps as early as four months, and those who got their own teeth late will have to be patient. Some babies' first teeth do not appear until they are over a year old! Non-phthalate formula. Actual product styling and colors may differ from product description.
