I have a Maya Wrap ring sling and a Solar veil ring sling and I had no luck with them at all...Okay the solar veil was easier because it was less fabric but still hard. I feel really bad about the Maya Wrap as it was a gift from my Mother and thus I don't want to sell it..will give it another shot this time around though.
I have a wrap from http://www.azurewraps.ca/
that I love. And will be my main carrier until we can do the hip carry in a pouch(with my son that was around 6 months)
I also had her custom make a beautiful Chinese Brocade Pouch this past the spring just as my son hit the weight limit for him being too heavy to carry by me That was around 25 lbs. Looking forward to trying that out.
I also own two other pouches a fleece adjustable and a regular stretch one that were testers for a WAHM shop that never opened but I used them both so much I think its time for a new one. Thinking about a Hot sling, a KK pouch or a Mama Kangaroo.
