It may look simple enough, but every parent knows that buttoning, snapping and zipping up baby’s pajamas after a diaper change in the wee hours of the morning can be anything but a cinch. That’s why we’re loving this subtle yet ingenious twist on baby sleepwear — the Knottie Baby Sleeper from Lalas Pequenos — which enables parents to quickly tie and untie the bottom in a knot, easily accessing a diaper that needs to be changed, and then swiftly returning tiny tootsies to a warm haven. Made with super soft organic bamboo fabric, the Knottie Baby Sleeper is available in sizes 0-3 months and 3-6 months. File this under: things we wish we’d had when our kids were still babies. Knot kidding.
