1. NIID UNO 2 Backpack ($100)
This fashionable bag wasn't designed to hold bottles and diapers, "but it may as well have been." It's made from a single piece of water-repellent fabric, and because it lies flat when unzipped, it doubles as a mobile changing station. Buy it at Amazon.
2. Removu K1 ($429)
"This is a massive upgrade over the VHS shoulder-brick camcorder your dad brought home when you were a kid." A self-stabilizing one-handed camera that shoots "buttery-smooth" 4K video, it can turn even a novice into an "Oscar-worthy" cinematographer. Buy it at Amazon.
3. Jack Black All-Over Wipes ($15)
Any guy on extended child-care duty might appreciate having wipes of his own. Made by Jack Black, a premium men's skin-care company, these moistened cloths will mop away sweat and dirt from head to toe, and leave a subtle scent of cologne. Buy it at Amazon.
Bonding time will be easy with a picture book that makes varied use of the word that's also its title. When a beaver and a platypus befriend a shark and go surfing, "dude" is the only word they need. Buy it at Amazon.
5. GrOpener ($16)
"A new baby means spare hands are hard to come by." But a dad with a one-handed bottle opener can crack open a few beers for himself and old friends even with Junior on his arm. The GrOpener also sticks by magnet to a fridge door. Buy it at Amazon.
