Although moby's have more of a learning curve compared to other carriers they are also the most comfortable for mom and baby. You are the one that wraps the baby up so you can make it as loose or as tight as you would like. Besides moby's can be used for back and front carry. Moby's distribute the weight of the child evenly so you do not have any straps digging into your shoulders or you back hurting after just a couple of minutes.
