Just to add to #2 and what wraps you can do with a shorter one - just keep in mind itâs shorter, so less times it can go around you and babyâs body, so short wraps are typically less supportive. Which is fine! Just depends on what youâre looking for. With a shorter wrap, youâre not able to cross under the legs and tie in front, since you just donât have the length, so you just have to be an absolute rock star at making the seat, since you donât have the cross passes under the legs for added security. With a 3 or even a 2, you can do a rucksack with a chest belt finish (candy cane chest belt or knotless finish), or a shepherds carry.
