• Structure: The wrap goes over one shoulder, across the wrappee's back from the top rail at shoulders to the bottom rail under bum, and over the wearer's opposite shoulder. It should support the wrappee from knee-to-knee. It looks the same in front carries as it does in back carries (although in front carries there are usually shoulder flips to keep the top rail from digging into the wearer's neck).

• Pros: Great for leaners (those wrappees that push against you and try to lean backward).

• Cons: Not as great for seat poppers (those that straighten their legs to slip through their seat) because the passes go over the wrappee's legs, leaving only the seat for support (which is totally adequate for non-poppers).

• Structure: The wrap goes over one shoulder, across the wrappee's back from the top rail at shoulders to the bottom rail under bum, and under the wearer's opposite shoulder/arm. It should support the wrappee from knee-to-knee. It looks the same in front carries as it does in back carries.

• Pros: It's a fairly solid pass for leaners as long as the top rail is high,

• Cons: Not great for seat poppers (those that straighten their legs) because the passes go over the wrappee's legs leaving only the hammock-like seat for support (which is totally adequate for non-poppers).

• Structure: The wrap goes over one shoulder, across the wrappee's back from the top rail at shoulders to the bottom rail under bum, and ends up under the wrappee's knee. It should support the wrappee from knee-to-knee. It looks the same in front carries as it does in back carries, although on the front the pass could be bunched (see examples of bunched passes below) like in Front Wrap Cross Carry.

• Pros: Helps prevent seat-popping from leg-straightening.

• Cons: Not great for leaners (those that lean back) because one side is so low.  Should be coupled with at least one more pass to close up the open side.

Once tied, a Wiggleproof Pass looks the same as a Cross Pass. Instead of starting at the wearer's shoulder, a Wiggleproof pass starts under the wrappee's knee, comes up across the wrappee's back, and ends over the wearer's shoulder.

• Structure: The wrap goes under one arm, across the wrappee's back from the top rail at mid-back to the bottom rail under bum, and ends up under the wearer's opposite arm. It should support the wrappee from knee-to-knee. It looks the same in front carries as it does in back carries, although if the pass goes across the wearer's front in a back carry it is called a Chest Pass, like in a Double Hammock.

• More info: A horizontal pass is always a supporting pass, coupled with other passes that help with leaning and/or seat popping. The only exception would be a Torso Carry and that should only be used it your wrappee is developmentally ready (ie has excellent torso control).

• Structure: The wrap goes under one arm, across the wrappee's back from the top rail at mid-back to the bottom rail under bum, and ends up under the wrappee's knee. It should support the wrappee from knee-to-knee. It looks the same in front carries as it does in back carries.

• More info: A reinforcing cross pass is always a supporting pass, coupled with other passes that help with leaning and/or seat popping. This is a great pass for seat poppers when coupled with another cross pass.

• Structure: The wrap is bunched up (make sure it isn't twisted) and spans from over the wrappee's knee, under bum, to end up over the wrappee's opposite knee. It should support the wrappee from knee-to-knee. It looks the same in front carries as it does in back carries.

• More info: A bunched cross pass is always a supporting pass, typically used as one of the last passes of a carry.

• Structure: The wrap is bunched up (make sure it isn't twisted) and spans from over the wrappee's knee, under bum, to end up under the wrappee's opposite knee. It should support the wrappee from knee-to-knee. It looks the same in front carries as it does in back carries.

• More info: A bunched cross pass is always a supporting pass, typically used as one of the last passes of a carry. It is often (but not always) coupled with a second bunched cross pass running in the opposite direction (so under the wrappee's opposite knee).
