Children begin teething around three to five months. You may notice an increase in drooling and a desire to chew on items. Sometimes, children may experience pain as their teeth begin to come in, and that may result in irritability. To help dull the pain that sometimes accompanies teething, parents can massage the child’s gum area for a few minutes or they can let him/her chew on a teething ring. Topical teething gels or Tylenol may also help dull the pain. Teething should not cause fever, diarrhea, sleeping problems or diaper rashes.​​
