For us, these ended up coming in handy for a reason that's totally unconnected to the season (that kind of rhymed). Baba G had an eye exam where he had to get his pupils dilated... and they freakishly stayed that way for nearly two days. Since he goes on a multi-hour stroller walk each afternoon, the sunglasses were key. But otherwise you'd want them so that your kid can play the role of a bad-ass, like so:
I had no intention of buying BG sunglasses, but got sucked into it when purchasing his wide-brimmed hat. That damn Amazon and its "recommendations." People seemed to like the Adventure BanZ brand (don't get me started on that z... or the fact that it's capitalized. Reminds me of this classic Ben Stiller/MTV sketch from '98 (2:55 mark, and wow, do I feel old now)).
But ANYWAY, we got the glasses at the same time we bought the hat, and when put together they put BG in full adventurer mode.
|Give me my own show on Animal Planet, already.|
The bottom line: I would assume baby sunglasses are nice to have when your kid needs to spend time in the sun and a wide-brimmed hat isn't enough (or isn't practical at the moment). They're definitely great for when your kid has an eye exam and has to stay out of brightly lit areas. The Adventure BanZ glasses have a wide, soft-elastic band which keeps them in place. But the reality is that we've only put these glasses on BG a few times in 7.5 months. When he has his daily stroller walk, he's already shielded from the sun thanks to both his hat and the sun shield that flips down on his stroller (which usually makes even the hat unnecessary).
It might just be that we aren't as outdoorsy as others who could find more use for kiddie sunglasses. Maybe if you went to the beach a lot they'd be indispensable. But that's not the case for us.
Does any else have baby sunglasses and actually use them?
