Safety 1st Finger Pinch Preventer
This is one of those things I wish I'd known about sooner. My 2yo son has a habit of closing house doors a little too roughly, and this whole time we could've been using the Safety 1st Finger Pinch Preventer as a precautionary measure.
It can be fitted on the hinge or knob side of a door, preventing those horrible finger pinches toddlers inevitably forget about. When not in-use, it can simply be hung from a doorknob for easy access later.
A two-pack of these pinch preventers is $9, while a four-pack is $15. Big thanks goes to Marco Arment for mentioning them in his recent toddler stuff review.
