Both sides now have sandwiched shoulders. If you try sandwiching the shoulders remember to keep more tension on the top part of the wrap rather than the bottom piece or you may lose the nice seat you created.
At this point, I have made the beginning of the criss cross on the child’s bottom (not shown) by bringing the wrap under my arm, then over the child’s hip, across his bottom and under his other leg. Then, I bring the end back to the front (the other end is tucked between my legs to keep the tension).
I cross the end over my chest, bringing it under the shoulder strap on the opposite side.
Do the same with the other side. You will now have an X across your chest.
Tie the two straps in a double knot and you are ready to go.
View from the side. This is also a great way to wear your wrap without any belly pressure or if your wrap is longer than you would need for this carry.
