Question:

- It is normal for a boy of 1 year and 4 months to have only two upper teeth that came out at 8 months; and down it has three teeth that came out at 10 months and a table that went down now at 1 year and 4 months. I am worried that the top has only two teeth and already has a table and some tables and two canines will come out. It is normal?
