This is one of several "All About" posts where each is about a particular type of commonly used baby carriers. I WANT HELP with pictures, comments and tricks to each brand you have experience with, how to use it properly, different carry options, and more! So please offer input to help supplement my information.
Mei tais (MT) are based on Asian style carriers worn throughout history. They are a piece of fabric with four long straps. Two straps form the waist and the other two are tied around the parent and baby to provide support. You can do front, back, and hip carries with them. MT brands usually differ in materials, body size, strap width, and strap length. Most of them can be used from newborn through toddlerhood, though some Mts are better suited for a certain size. Mts can be worn by everybody, but do check the strap length if you are a fluffier since some shoulder straps are as short as 70". I've seen Mts with strap lengths as long as 90"! A longer strap length does give more options for tying, but a petite mom may find it overwhelming.
