Height

Our family was gifted with a lot of height (some of us, anyway, right, Saralyn?), so the topic comes up in conversation now and then.  My sister and I brought shame to the family when we both married men under 6 feet tall.  I know, how could we?  Those who are less than tall are subject to lots of rude comments when the family gets together.  The height comparisons in these pictures started innocently enough.  Basia and Alyssa are only 5 weeks apart in age and have always been pretty similar in height.  We noticed on this visit that Alyssa has gained a couple inches on Basia, and I suspect it's going to only get worse.  Can you guess who in these pictures is standing on a very tall chair?
