OK so I bumped up a level because I figured you guys have probably been through this debate already...So I fell in love with these cute fireman rainboots that match my almost-2-year-old's rainjacket. He wears a size 7 now, but I thought maybe I should size up to an 8 so they'll last through the spring, since it's the kind of item I know we won't get too many wears out of anyways. But then it seems silly if he's pretty much swimming in them for now... So what did you guys do? We do like to go outside a lot in all seasons, but how much of a necessity are rainboots anyways?
