It's amazing how this little guy has changed in just a couple of years.  He's full of energy and always smiling.  But that night was different.  The little boy I knew who is always giggling, hamming it up and running around sat quietly.  Just shy of two years old, this little guy sat perfectly content to stack duplo blocks.  He sat their completely focused on his duplo tower, determined to use his little fingers to stack each block.  How sweet is he?!
