I used to carry my babies in a ring sling during really hot weather (of which, we do not get an awful lot where we live!) but Kaelan does not like the ring sling or being held on my hip. Up until now, he's been carried mostly in my DidyTais which are mei teis made from the same woven material the Didymos wraps are. I could wear my wraps even in the summer, because they breathe well, but the DidyTai is even lighter weight, since I don't need to wrap the fabric several layers thick. It is just one light layer. Unfortunately, Kaelan has gotten so heavy, I am starting to have a lot of back pain and can't wear him for more than 30 minutes at a time. So, I pulled my Ergo out the other day. It distributes the weight down on to my hips instead of across my back, so I was able to wear him for up to 3 hours without any back pain. But even though it was only a mildly warm day (about 22 C), he and I were soaked in sweat. I'm now on the look out for a lighter weight carrier that supports his weight as well as the Ergo. I may have to try my wraps again and see if they don't do a better job for my back than my DidyTais do, much as I love them!
Has anyone tried a Beco Butterfly 2? Are they terribly warm? I've been babywearing for over 15 years (my own five as well as babies I've babysat) but I've never managed the back carry in any of the wraps, slings or carriers I've used. I've watched so many how-to videos and have tried and tried, but I simply do not have the range of movement in my shoulders that it seems necessary to get the baby on my back. I was looking at the structure of the BB2 and it looks like I could actually accomplish the back carry with that one. Kaelan is just too heavy for my back these days and, much as I love carrying him on my front where I can snuggle with him and kiss his sweet, fuzzy head, it's much harder on my back to front carry him.
