This is a baby wrap that can be used from newborns. I purchased it around 2020. I used it until around the time my baby could hold their head up. You just wrap it, so both parents can share it regardless of their build. My baby seemed to feel secure being wrapped up, and would fall asleep quickly when held in the Boba Wrap. Individual results may vary. I used it for six months, so there may be some wear and tear, but I was careful about keeping it clean, so I think it's fine. It has been home-cleaned. The following is a copy of the official website description: The Boba Wrap has no buckles, straps, or snaps. It's the ideal baby carrier for newborns and babies. Simply wrap the single piece of fabric around your body for a close fit. It creates a sense of security, as if the baby is back in the womb. It's one of the few baby carriers that can be used immediately after birth. The simple design of "just wrap" has no attachment parts. The special single piece of fabric comfortably wraps both the baby and the wearer. Because it's a single piece of fabric, it doesn't dig into the shoulders or waist, and evenly distributes the baby's weight.
