A tie on carrier is known as a mei tai. Based on the traditional Asian carrier, a mei tai is basically a rectangular piece of material with 2 waist straps and 2 shoulder straps. They are simple to use because they are just tied on using basic knots. With a mei tai you can carry your baby on your front, back or hip. Mei tais are suitable from newborn to toddler and are useful for parents wishing to share a carrier. For more detailed information on mei tais, please see our "Sling Advice" section.
