My favorite part of the carrier is that there is a seat for baby, she’s not dangling by her bottom half she’s completely comfortable, the carrier does not hurt my back at all, i have short arms so bucking the clasp is tricky but that’s my fault for having short arms, but it’s by far the best for my baby and the fact that she’s not dangling by her crotch or uncomfortable in any way they made it perfect for baby and A+ for backs
