time goes too fast, part two.

it really does.  we are approaching arlito's 4 month birthday (too fast too fast!).  more than anything, more than laughing, than sleeping through the night (though we're still not there, and seemingly moving farther away than closer), more than anything, four months old seems like a milestone.  a quarter of the year.  plus, he was born in spring, and now summer is ending.  plus, when he was just a week old, and sleep was a foreign land, it seemed like he would never be ONE month old, and now i've lost track of the weeks.  i think he is 16 weeks today, but i could be wrong.  does that make me a bad mother?
