My baby turns three tomorrow. How is that possible? Ok, I get that it's possible for him to turn three. It feels like he's been around forever, so I don't doubt that it's been at least three years - sometimes it feels like 18 years and can't he go to college already - but how on earth am I so old that my baby, THE baby, turns three? Huh, maybe this is really about the fact that my birthday is on Sunday.
