Growth spurt

Amazing.  Within the last few weeks, Diego has somehow outgrown his size 6 pants and now wears a size 7.  He's been complaining about being squeezed and I finally got wise and pulled out our size 7 stash and three of the five pairs fit perfectly. 

How does that happen??  Though I have thought he looks so much taller and just bigger recently, eyeing him up and wondering how he was ever such a little guy like his baby brudder.  So close, so far away...
