The pain associated with teething often causes babies to wake during the night. Dr. Jennifer Gardner, a pediatrician and founder of Healthy Kids Company, says that acute teething pain can last up to 72 hours. “Once the tooth is through, the pain decreases quickly and baby’s sleep patterns should return to normal,” she said. Gardner recommends using cold, hard objects to ease babies back to sleep, such as cold rubber BPA-free teething rings, frozen washcloths, frozen veggies or fruits in a mesh feeding bag, or Popsicles if the baby is older than 6 months. Be sure to supervise your baby at all times for choking hazards, and check with your pediatrician before using any form of pain reliever.
