What are the advantages and disadvantages of different waist styles? All the waist styles are comfortable to wear but there there are subtle differences between them. Below is some information to help you choose.
All of my carriers have a padded waist. When worn non apron style. a padded waist helps to transfer your child's weight to your hips rather than your shoulders. Padding can also prevent the waist band from digging in when worn to carry heavy kids. The waist is not too thickly padded though so you can also wear it apron style if you prefer. Wearing apron style (and sometimes rolling the waist too) is handy for shortening the body of the carrier when wearing with a smaller baby.
This is an option for meh dai's/mei tai's , half buckles and reverse half buckles (buckle shoulder straps). Pictured below is a reverse half buckle. I usually sew this waist as a continuous length double layer (11cm wide). Sometimes there is not enough continuous length in a wrap for this so I can usually get around that by sewing the waist in three parts and the ties can be double layer (11cm wide) or single layer wrap style ties. I will also sometimes sew this waist in two parts (joined in the middle of the wasitband) with double layer ties. It just depends on how much continuous length available in your wrap. If you have a preference just let me know.
Advantages: Can reduce the muffin top look (especially if you have single layer ties) as you can spread the straps out across your stomach. If your waist ties are long enough you can thread them through the shoulder straps for a waist free carry. A tie waist is very easy to share between different sized wearers.
Disadvantages: Can take a little practice to get the waist tightened effectively. Takes slightly longer to put on. You need to check you are untiying the right knot when taking baby down (shoulder straps should be untied first).
