I recommend this Health Canada baby carriers and slings page to everyone that uses baby carrying products. It outlines risks, safe placement of baby, and safe use a carrier.
Wrap versus ring sling
Choosing a wrap length
Wondering what length of wrap? This depends on your size and what carries you want to do. A “base size” wrap allows the highest number of carries, and is 4.8 metres for a women’s medium shirt size. A medium sized ring sling is 1.75 metres long, which takes 2 metres of fabric.
How to use ring slings and wraps
One of the wonderful and unique things about woven wraps is that they allow you to carry your baby in a variety of front, back and side positions, with weight distributed in different places depending on the carry.
To learn carries, I recommend watching tutorials by certified babywearing educators (e.g., Wrapping Rachel’s how to use a ring sling with a newborn) and/or attending a local babywearing group.
As for which carries, I recommend starting with basic front carries (front cross carry), then more advanced front carries (kangaroo carry) and side carries (traditional sling carry), then graduating to a simple back (ruck) followed by a more advanced back carry (double hammock).
