Michael (3) smells good. I like to go in and sniff his face and hair when he's asleep. (He smells good when he's awake too, but he's more likely to hit me then.) Too bad it doesn't last long. Andrew (6) isn't stinky yet, but he doesn't have that fresh kid smell anymore.
Sniffing your kids is a very nice and frequently undocument perq of being a dad. I'm enjoying it while I can.
