  2. Pain, fever, or other negative reactions to teething. Quite often, teeth in infants are cut with the appearance of such symptoms. For their relief, parents use cooling gels, teethers, antipyretic drugs.
  3. Failure to try lure. Many kids prefer mother's milk to different complementary foods, which is very frustrating and troubling for parents. Forcing a crumb to try to lure by force is impossible, but you should not stop offering new food either.
