Double Rebozo Shoulder to Shoulder is most commonly shortened to DRS2S.
This is exactly what it sounds like; two rebozo passes with a chest belt that goes from one shoulder to the other. This is typically done with your base size. You can choose to do it with a shorter wrap as I have, it just means you will have to tie under their bum instead of around your waist.
This is an okay carry for me, but the half knots on my chest caused a bit of pressure. I would caution nursing mothers with a predisposition for blocked ducts and mastitis to be careful with this carry or skip altogether.
