I'm getting our online orders together for our trip to the US next month (got to love that strong Can. $) and coincidentally saw this at Target: http://www.target.com/Protect-Bub-UP...a%20bub&page=1 It seems to be a sunshade for a convertible carseat. Is this a bad idea in terms of after-market, and flying projectiles? Or is it safe to use? It'd be nice to be able to block some of the sun, especially so DS could sleep on longer trips. But not if it's unsafe.
