Yep, that's right, he's a year and a half old and he's practically (not) skiing.  He's actually on a ski trainer that we've been using with the older "littles".  Boden saw it on the beach and grabbed the handle and put his feet in the bindings.  Todd seized the opportunity and started pulling him around.  I wouldn't say he loved it, but he definitely didn't hate it.  Next year, I think we could have him behind the boat.  This year, we'll stick to pulling him around the shore and encouraging him to wear his lifejacket.  At this rate, he's going to be barefooting by the time he's in kindergarten.  I am definitely envious.
