I’ve been baby wearing face in with my now 8 month old in an Artipoppe. How important is maintaining a C shape spine in an 8 month old. For the life of me, I can never put her in a C shape. Not sure if it’s her extending her back or if it’s something I’m doing wrong. Even when first putting her in with the straps still loose, her spine is already extended. She’s a petite 8 month old probably still in the 5th percentile for height and weight.
