The Lark Baby Carrier fits babies weighing 10–45 lbs and wearing size 3-6m tops or larger: generally babies ages 3 months through toddlerhood.

The Lark Kid Carrier fits toddlers weighing 25–65 lbs and wearing size 3T tops or bigger: built bigger and stronger for toddlers through preschool and beyond.

Both are buckle carriers with front and back carry. See our full buckle carrier guide by baby stage →

Yes! The Lark Baby covers most kids up to age 3 and up to 45 lbs. Once your toddler is wearing 3T tops and wants more knee-to-knee support, it's time to size up to the Lark Kid Carrier! Learn more in our toddler babywearing guide →

Up to 65 lbs, which is a solid preschooler, but sometimes longer! Our customers regularly carry 4- and 5-year-olds in the Lark Kid on hikes, at airports, and when tired legs strike.

The Lark is designed to provide substantial support for your baby's bottom and thighs, which is what matters for healthy hip development. Unlike ring slings or wraps, where you actively position baby into the deep M shape, the Lark's structured panel does that work for you. As long as their bottom is supported and their legs aren't dangling, their hips are well-positioned.

The IHDI stopped accepting product submissions for certification before the Lark Baby Carrier was developed, so it has not been formally certified.
