My son is 8 months old and still has only one tooth. I am worried. Do I need to consult a doctor?

Hey, Do not worry, my daughter started teething at 11 months. Since, all kids have their own body type and they take their own time to reach the developmental stages. But in any case you can discuss with the baby's paediatrician. Sometimes, listening from doctor's mouth rests all your anxiety than any one else.
