A few of my favorite things:

Seeing my boys run around in their undies, usually at night before bed. DD is just so think and lanky- he'll make a good track runner someday. Sam, on the other hand is a bit chubbier, and looks so cute in his little 2T undies!!!

Sammy saying two and three words at a time. They're so cute! He has a way of distinctly pronouncing 'th' words: other, father, 'nother. It's so cute!
