Teeth

Shawn had only 4 teeth for the longest period of time.  Think till he was 15th month old.  Now, at 19th month plus, he has 6 on top and 6 at the bottom.  Compared to others who already have a full set of teeth, Shawn is a little behind time.  Nevertheless, mummy is still happy to see all his little pearlies popping out as days go by.
