Ring sling help

Hi I've been given a "original nojo" ring sling andiI can't figure out how to use it

There   doesn't seem to be any videos online demonstrating it.

I have a 7- week old and she's got reflux so I thought keeping her upright in a sling could help, but I can only put her in this sling lying down and even then she's kind of curved around me rather than straight... Is it just this style of sling or am I using it incorrectly?

If anyone has advice or a link to some instructions that would be great.

Thank you!

Thanks for responding Fallen, but these videos aren't about the Nojo sling. The nojo sling is a different design and doesn't work in quite the same way as the flat fabric slings.

Cheers
