If you just found out your kid is a leftie, most of the world we can adapt to. But something that will make their school years easier, as well as their crafting ability, is left handed scissors. Once I got my pair, I found it was individually easier to cut things out. Try it - the typical pair is molded for a right hand, so it cuts into your thumb over extended use. But the worst part is the way the blades connect - you can't see what you're cutting! You have to hold your left hand far over your body's right side, or crane your neck over your hand to see what you're cutting. Otherwise, you just guess and it looks sloppy.

Keyboards, pianos, drums, doors, manual cars, all of this can be overcome. But scissors? Lefties need leftie scissors. I'm still using my pair 30 years later and they're worth their weight in gold.
