Lullahug ad: Jennifer Miller

The ache isn't the baby's weight. It's the angle. Hold a 20-pound toddler out in front of you and your lower back reads it closer to 60. Every inch away from your body multiplies the load. That's leverage. Not age. Which is why borrowing your kids' hiking-style carrier makes it worse. Two stiff straps pull the shoulders forward, and the lower back spends the whole visit fighting to keep you upright. The Lullahug Sling works the other way. One extra-wide padded strap runs diagonally across the torso, so your grandbaby sits against your body instead of hanging off the front of it. One click buckle. On in five seconds. Newborn to a 50-lb toddler, in soft breathable cotton. Over 150,000 grandparents carry this way.
