What is a Meh Dai/Bei Dai?
A Meh Dai (pronounced Meh Die) is a square or rectangular panel of fabric with long straps that you tie onto your body on the front or the back. Since it ties on a meh dai does not need to be sized, making it a good choice if you are sharing the carrier between different sized people. Extra long straps are available on many brands, and panel shapes vary. Additional options include headrests, hoods, or toy straps. A wrap conversion is a meh dai made from a woven wrap.
Pros: Meh dais are supportive carriers that many people find just as easy and comfortable with a newborn as they do with a toddler. If you only want to buy one carrier to last for your entire time babywearing, consider a meh dai.
Cons: Long straps may drag on the ground during tying. (Try stuffing long straps in pockets while you are getting the carrier/child positioned!)
