I LOVE my Natibaby woven wrap, but I'm afraid it will be too hot for the desert. I've used a narrower gauze wrap during hot days with my first, but she was about 6 months by that time and could hold her head wrapped with legs out. My gauze wrap just isn't wide enough for some of the NB carries I like with the woven. Thinking I will get a new cut of gauze fabric that is wider, and have it serged.
I also have a mesh-style RS that is great for the summer and being in the water, just not padded for extra comfort. Also, I never used a RS with DD until she was bigger, so not sure how I will feel with a small NB in it.
