When does the first milk tooth fall? My friend's daughter who is barely five lost two of hers last week? Am afraid my four-year-old will also lose hers early.

Each child progresses at a different pace. Some children lose their teeth even before they turn 4 years old, whereas some children only lose their first tooth at age 5 or 6. http://sg.theasianparent.com/tooth-loss-in-children/
