How tall are they?

I measured Bobby and Emmy at the science museum yesterday.  They are 41.5 inches (Bobby) and 45.5 inches (Emmy).  The height predictor says Bobby will be 6 feet 1 inch based on his current height and Emmy will be 5 feet 3 inches.  Sorry, Emmy.....you are destined to be short like your mom and will have to rely on your speed, agility and attitude to get ahead in sports :)  It's not so bad - I speak from experience!
